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.

Using Voronoi polygons for simplified continent generation
Well, the easiest option would probably be to use a different Delaunay/Voronoi library. Delaunator (C# bindings here) should be a pretty good option: it's fast, and there's a good explanation of how to use the data structures it generates. There is some weirdness with how points at the edge of the domain work that you may have to work around, but that will probably be easier than trying to modify another algorithm or write your own. I know I've struggled to implement the algorithms for calculating Voronoi diagrams/Delaunay triangulations, even though I feel like I have a decent high-level understanding of how Fortune's algorithm is supposed to work.

Visualizing Delaunay Triangulation
Great article!
How does this algorithm compare to others, e.g. sweep algorithms like the one used by delaunator[0]?
An obvious difference is sweep algorithms sort the points in some way before adding them, is that a key to efficiency gains?

NYC Subwaysheds (Travel Time Maps)
Isochrones are manually calculated using turf.js assuming 1.2m/s walking speed after the subway trip. These are simple buffers around each station/prior isochrone and do not take the street network into account.

Getting the distance from point A to point B.
Not to take away from you learning, which I think is awesome, I was wondering if you know about http://turfjs.org/ which provides a lot of simple modules … and is surprisingly hard to find. Their `distance` modules may be relevant in this case.
