SPaTo Visual Explorer is an interactive software tool for the visualization and exploration of complex networks.

By reducing a network to the shortest-path tree of a selected root node, we obtain a local but simpler view of the network that can be easily visualized. With the ability to quickly change the root node, the program allows us to explore the network from different perspectives.

We have prepared a short introductory video showing an example of what shortest-path-tree tomography is about and what the software can do.

The method and software were developed by Christian Thiemann in the research group of Dirk Brockmann at Northwestern University, financially supported by the Volkswagen Foundation and the European Commission.
