Mapping Britain with Telephone Calls

Telephone calls and regional connections in Great Britain

These maps are fascinating. Have you ever wondered why state or county or city boundaries are drawn where they are? It turns out that administrative and government boundaries are consistent with trends in human relationships; that is, people associate most with others in the same government-defined region. To investigate the geography of human relationships, a […]

Topologies of Linux and E. coli Control Networks

Comparing genomes to computer operating systems in terms of the topology and evolution of their regulatory control networks

A comparison of the Linux call graph hierarchy with the E. coli regulatory network. Researchers at Yale discovered that the Linux control structure is top-heavy, with a few common modules reused often. E coli, by contrast, has limited central control with many specialized “workers” at the bottom of the hierarchy.

Graph Visualization with Edge Bundling

US air transit routes after bundling algorithm was applied

We recently encountered (via infosthetics) a paper from Danny Holten and Jarke J. van Wijk that demonstrates an algorithm for creating beautiful graph visualizations. The original paper is Force-Directed Edge Bundling for Graph Visualization, published in 2009. In computer science theory, a graph is a collection of nodes and the edges between them. Graphs are […]

Jason Salavon


We find the work of Jason Salavon highly inspirational. At the intersection of art and visualization, his images are distinctive for their surface and immediate graphical language while also communicating significant stories of process and history. By merging dozens or hundreds images that share some common theme, Salavon helps us extract high-level information about common […]

Song Visualizations with Echo Nest

Philip Glass String Quartet #5, 2nd Movement

We recently came across Anita Lillie’s beautiful music visualization and MusicBox projects. The music visualization project was especially intriguing to us, since it was the only music visualization project we’d seen that did not require video playback—the visualizations were strictly in 2D. Unfortunately, the source code for Lillie’s visualizations was not available, so we decided […]

Painting Supernovas

Supernova Zoom

Christopher Healey and his research team have developed a painterly approach to data visualization. His software correlates dimensions of multivariate data to dimensions of visual sensation. The results are stunning and have both artistic and scientific merit. In the images shown here, Healey’s software has been turned to the task of visualizing data from the […]

Feltron Annual Reports

Map and timeline from the Feltron 2008 Annual Report

The Feltron Annual Reports are brilliant personal visualizations that describe, one year at a time, the life of Nicholas Felton. He uses an elegant combination of textual manipulation, charts, and diagrams to convey interesting and sometimes trivial facts about his life. We learn that the subway fees are 93 cents on the mile, compared with […]
