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.
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 [...]
Visualizations show relative pitch strength across the duration of the song. Colors scheme is derived from the Kid A album cover. Song analysis by Echo Nest via the Echo Nest Remix toolkit. Rendering was done with PyCairo.
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 [...]
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 [...]
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 [...]
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 [...]
