Hello ladies and gentlegerms, Here is a video of a growing shortet path tree from an intersection just south of the University Bridge in Seattle toward all points in North Seattle, using Graphserver and OSM street data; visualization using Processing. Nino Walker and I have made some great progress in writing a set of Python wrappers for the Graphserver library, making things like this relatively straightforward to implement. While pre and post-processing of the graph took several seconds, and the process of making this graphic is not completely automated, the Graph.shortest_path_tree() function that produced this graph returned in 0.03 seconds.
