Ski Graphs

I recently went skiing, and the process of studying the trail map and picking out routes got me thinking about how a ski resort is basically a big directed graph.

This inspired me to make a little widget that would find shortest paths between two points in the resort. The result is a simplified version of Heavenly that doesn't include the parts that were closed when I was there and also doesn't include advanced terrain that I can't ski down (yet). The grey edges are the chairlifts, and the other edges are the runs color-coded by level.

To find a path, click on a start and end node. You can check out the completed code here.
