We recently released a new major version of GLEAMviz. This application provides a user-friendly interface for using the GLEAM engine, a server-side simulator of the spreading of infectious diseases on a global scale.

Version 3 of the GLEAMviz now provides the Simulation Builder, a new interface for setting up the simulations, and two new visualizations.

Simulation Builder interface.

The first new visualization is based on the SPaTo visualization developed by Christian Thiemann. I adapted this visualization to fit the specifics of the infection spreading data generated by GLEAM, and reimplemented it for integration in GLEAMviz. The visualization shows the shortest-path tree among the cities with airports, either using a geographic layout or a concentric layout (with or without logarithmic scaling). Animated transitions are provided when the user changes the layout.

The second new visualization uses an interactive 3D representation of the world. The incidence spreading is shown as an animated texture, while the initial seedings are shown as 3D arcs.

Accompanying this new release I also worked on a new gleamviz.org website and promotional material.
