Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Then I stumbled upon Dijkstar, which is an implementation of Dijkstra in python that has the ability to pass in your own heuristics function to customise how it runs. In this case the default behaviour gave me exactly what I needed and even returns total cost.

This limitation did give me an excuse to implement Dijkstra's algorithm from scratch, which was fun; it also allowed me to play around with the pqueue library, which is very convenient although also imposes its own set of constraints that require the user to have a good amount of foreknowledge about the data they plan to insert into the queue. Since I didn't have that for this problem, I chose a pessimistic heuristic that doesn't seem to impact performance much for the data sizes we're dealing with here.
