This small example illustrates dot's feature to draw nodes and edges in clusters or separate rectangular layout regions. Clusters are encoded as subgraphs whose names have the prefix 'cluster'. The color attribute of a cluster is interpreted as its outline color or its background color if its style is 'filled'. Mdiamond and Msquare are modified symbols for data flow diagrams.

Diagrams developed to represent color systems. In 1758, Mayer developed a system of constructing and naming many of the possible colours. Lambert extended this with a 3D pyramid indicating "depth" (saturation).

Lambert wanted to extend the coverage of the system to include the concept of depth. He believed that the colour pyramid would be useful to textile merchants to decide if they stocked all the colours, and to dyers and printers as a source of inspiration.

Bryce Glass has developed a series of delightful Flickr user model diagrams where one can easily understand the Flickr ecosystem and the full potential of the popular photo-sharing service. In October 24, 2005, Bryce posted this original diagram in his blog (Soldier Ant), which ended up becoming the first of a series of iterations. The latest version (v0.3) has several new elements, such as comments, rss feeds and blogs, but I still prefer the intact purity and simplicity of the original version (shown here).

On his post on October 24, Bryce explains: "I've been doing some concept diagramming for work lately, and I've found myself enjoying it immensely. (...) However, since it's for work I can't share much of it. I did post some sanitized versions, with all the object-names obsfucated, but that just didn't seem wholly satisfying. So over the weekend I invested some time in a diagram that I can share with the internets: a simple Flickr user model (regrettably incomplete -- but I realized that if I tried to include the whole Flickr-verse that this diagram would go beyond labor of love and straight into excercise in folly)".

The chart tracks the 'Information Economy' by dividing the U.S. labor force into four sectors: agriculture (in green), industry (blue), information (red) and service (orange).

The vertical scale shows the percentage of the total labor force held by each sector.

From 1800 through 1900, agriculture was the dominant employer in the economy. By 1910 it was industrial jobs and by 1960, information was the primary sector of the labor force.

This remarkable graph shows a travel-time map from an issue of the Japanese magazine Shukan Asahi. The shortest travel times (not counting waiting time) from Tokyo to various points around Japan using airplanes and trains were plotted in this deformed map. Data was taken from the 1969 issue of the Japan National Railways timetables. Coordinates for the various areas were determined by time coordinates using concentric circles centering on Tokyo and by topographical directions centering on Tokyo. To obtain an accurate concept of the space in this deformed map, one ought to conceive a topographical map like a prune that is all shriveled up.

The father of all subway maps, the London Underground map, was the brainchild of Underground electrical draughtsman, Harry Beck, who produced this imaginative yet stunningly simple design back in 1933.

Beck based the map on the circuit diagrams he drew for his day job, stripping the sprawling Tube network down to basics and ignoring the exact geographical location of the tube stations. The result was an instantly clear and comprehensible chart that would become an essential guide to London - and a template for transport maps the world over.

Beck's revolutionary design, with certain modifications and additions, survives to the present day and is set to serve London Underground and its millions of customers for many years to come. The first image represents Beck's original map from 1933, while the second image shows the most up-to-date version of the London Underground map.

"Mark Lombardi (1951-2000) draws on the major political and financial scandals of the day to create large-scale linear diagrams that at first glance look like celestial maps; a closer reading reveals the intricate web of connections that lurk beneath current headlines. From Whitewater to the Vatican Bank, Lombardi uses dotted lines and broken arrows to chart the paths of illicit deals and laundered money, keeping track of it all in a handwritten database of 12,000 index cards. By scrutinizing the mutable boundaries that separate artistic practice from daily life, Lombardi wrings visual poetry out of dirty secrets--the results are a chillingly beautiful guide to the facts of life."

Networks can be represented in many different forms, each of which may be projected into different mathematical spaces for analysis.

Node-link diagrams can expose network vulnerabilities, highlight optimal paths, and cluster nodes for analysis. Radial formats provide alternate ways of layering, integrating, and navigating networks. Quantitative icons can help to explore the dynamics of interacting subnetworks.

Radial formats provide alternate ways of layering, integrating, and navigating networks. This “combination lock” approach to decision making uses stepwise combinatorics to selectively navigate a solution space.

Other network representations include more conventional node-link diagrams that can expose network vulnerabilities, highlight optimal paths, and cluster nodes for analysis, and even quantitative icons that can help to explore the dynamics of interacting subnetworks.

Network visualizations can take unexpected forms, such as discontinuous yet related glyphs for wayfinding through regions with varying resources.

Other network representations include node-link diagrams that can expose network vulnerabilities, highlight optimal paths, and cluster nodes for analysis, as well as radial formats that provide alternate ways of layering, integrating, and navigating networks.

Layering and integrating networks presents information in a form for rapid analysis. Layers may consist of different network representations, such as node-link diagrams, radial formats, and quantitative icons.

Node-link diagrams can expose critical network vulnerabilities and highlight optimal paths.

Networks can be represented in a multitude of forms quite distinct from node-link diagrams. For example, radial formats provide alternate ways of layering, integrating, and navigating networks, and even quantitative icons can help to explore the dynamics of interacting subnetworks.

Mark Lombardi (1955-2000) was an abstract painter, best known for his network diagrams of crime and conspiracy. Lombardi's drawings attempt to document financial and political frauds by power brokers. Nodes in the diagrams represent individuals, corporations and government agencies, connected by lines showing associations, deals and so forth.

His 1999 drawing, entitled George W. Bush, Harken Energy and Jackson Stephens, ca 1979-90, shows the proven connections between James Bath, the Bush and bin Laden families, and business deals in Texas and around the world. Thirteen lines originate with or point to James R. Bath, more than any other name presented. Among those linked to this obscure yet central character are George W. Bush, Jr., George H.W. Bush, Sr., Senator Lloyd Bentsen of Texas, Governor John B. Connally of Texas, Sheik Salim bin Laden of Saudi Arabia, and Sheik Salim's younger brother, Osama bin Laden.

Lombardi's other network diagrams relate to the Iran-Contra Affair, World Finance Corporation, the Bay of Pigs invasion, and so forth. Each was based on thousands of notes gathered from news reports and written on index cards.

Venn diagrams are often used in logic to show intersection relations among sets, but they are usually limited to being shown as three overlapping circles.

Here (http://www.combinatorics.org/Surveys/ds5/VennSymmEJC.html) is a page that explains a general way to construct symmetric Venn diagrams using ellipses. The example shows a Venn diagram made from 5 congruent ellipses. The regions are colored according to the number of ellipses in which they are contained: grey = 0, yellow = 1, red = 2, blue = 3, green = 4, and black = 5. Note that the number of regions colored with a given color corresponds to the appropriate binomial coefficient: #(grey) = #(black) = 1, #(yellow) = #(green) = 5, and #(red) = #(blue) = 10.

Open source software, such as Firefox, Linux, and Eclipse, is created collaboratively by a group of individuals who make the code accessible to the public to both use and enhance. Seeing the pattern of contributions to these projects can provide useful insights into the vitality of the project and the community building it. The Bloom Diagram provides a visualization of contribution activity in open source projects. At a glance, this tool can summarize the overall level of coding and discussion in a project, show which individuals are the recent key contributors, and allow comparisons across multiple projects.

The Bloom Diagram is being used to study Sourceforge.net, one of the most popular open source community sites, and the IIOSB (the IBM Internal Open Source Bazaar), a site hosted internally within IBM to promote open source-style development. The screenshot below is an example of the Bloom Diagram for a Sourceforge project. The upper left portion provides summary statistics about the project, for example the total number of events by commentor and coder. Using the slider in the timeline, top right, users can see the state of the project at different points in time. Users can also play an animation of the activity over time from this timeline. The inset on the bottom left is a live "magnifying glass" view around the current mouse position. Keyboard controls are also available to let users zoom in, out, and pan around the screen.

This diagram gives us a clear sense of the overall proportion of coding to commenting activity in this project. The inner ring, which represents code events, takes up slightly more than a quarter of the circle. One quarter of the outer ring, which represents comment events, overlaps with the inner ring, revealing that only 25% of the community is commenting and coding. The majority of contributors (75%) are just discussing the project.

When the user moves the timeline slider, animated bubbles appear in the inner or outer ring. A bubble in the inner ring represents a code event, while a bubble in the outer ring indicates a comment event. The bubble position as it animates provides a cue about the frequency and recency of the event. If the person associated with the event seldom contributes code or comments after that event, the bubble drifts outward, leaving a "trail" (a series of unfilled circles). If the person continues to create code or comments, the bubble moves back to its starting position, creating a "bounce-back" effect. Judging from this diagram, there seems to be a core group of developers who frequently contribute code (25% of the bubbles in the inner ring are bouncing around the center) and a peripheral group of people commenting on the project less frequently (75% bubbles in the outer ring with fewer bouncing toward the center).

Bloom Diagrams can provide useful insights into how things are going on a project. For example, project leads can use them as a dashboard to monitor how often people are contributing and follow up when contributions start to slow. Potential contributors may decide whether or not to join a project depending on the activity they see. Hosting providers of open source projects can identify the hot projects to promote on the front pages of their community sites or check on the ones that seem to be dying down.

The Natto View proposes an effective use of the third dimension, taking full advantage of the Z axis: drawing diagrams in two dimensions and reminding the third dimension for interactive manipulation.

The project is a set of 3D interactive visualizing techniques and provides dynamic focus+context operation for graph structure such as the World Wide Web. Information nodes, or HTML documents, are placed on the fundamental floor-plane in 3D space, and users can select and move arbitrary node with direct manipulation. As the user lifts a focused node up, the nodes to which it links are lifted up together, and thus complicated networks are disentangled dynamically. By three dimensional perspective technique, the user can view both details of information connections near the selected node and global context of the large information space like fisheye lens model. The differences of the Natto View from most of other graphical visualization are: It supports not only visualization but also interactive and dynamic manipulation on users' demand. It is a layout-independent method and thus suitable for dynamic enlargement of diagram such as incremental access to huge distributed information networks.

Weather maps can also use non-geographic, topological diagrams to represent the network structure.

This example diagram shows the traffic load on the GARR-B network in Italy.

Network diagrams are often used to show the relations between pairs of objects. Among other difficulties, it is hard to produce a pleasing arrangement of the nodes and links, and hard to use a network diagram as a data display.

Krempel and Plümper used the geographic distances among 26 countries with a spring-embedding algorithm to obtain a simplistic geographical layout. They fit a series of regression models predicting the amount of bilateral trade between these countries, and used the network diagram to show both the data (trade volume) and the residuals (errors) from a given model. This visual procedure was used to suggest additional variables to be included into the models.

The network diagrams show the volumes of bilateral trade (sizes of the arrows) and use colors to depict the errors of a given model--- which countries trade more than estimated (orange, red) or less (green, blue). The size of the country symbols stands for their volume of trade (in $ US), the balance of trade can be read from the comparision of the imports (bottom) and the exports (top). The pie slices indicate the degree to which the volume of the imports and exports (size) of a single country are overestimated respectively underestimated (colors).

Model 2, which accounts for geographical distance and the GDP of the importing and exporting countries, shows a systematic regional imperfection of the estimates for the Pacific region. An enhanced model accounts additionally for joint borders, joint oceans regional economic areas and yields an improved fit. Nevertheless one can easily detect a systematic component in the errors, which points to the importance of the former British Commonwealth (GBR - HKG - AUS) for which the trade volumes are systematically underestimated.
