Geospatial-temporal visualizations

Visualizing the distribution of Lyme diseases in 3D reported in the U.S. in 2005, 2006, and 2007 by the CDC. One might argue that a county-level choropleth map would be a suitable presentation. Nevertheless, it would be hard to argue that a county-level choropleth map using hue or brightness could reveal the threefold increase in Lyme disease cases centered around New England vs. the Midwest.

Networks and structures

Visualizing causal relationships of 20 popular diseases (left) from reactome and HIV life cycle (right): Gradient links indicate causalities between biochemical reactions.

Dynamic network visualization

Major events from nearly 100,000 political blogs in last 10 years were automatically detected in our visualization: Links connect popular terms appeared in the same blogs.

Matrix visualization

Visualizing the alignment of taxonomic classifications: Gymnospermae sec. Weakley (2010) vs. RAB (1968)

High-dimensional data are represented by a small subset of variables in the US unemployment rates (left) from BLS and in the Asteraceae taxonomy (right) of 2,048 characters.
