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.

I read the full-GitHub-flavored markdown spec so you do not have to. GitHub natively supports many lesser known features including the ability to create diagrams, maps and even 3D models, directly from markdown text.
GitHub also supports GeoJSON and itās topology extension TopoJSON. Creating interactive maps could not have been simpler.

Show HN: A simple world flags game, my first web dev project as a beginner

My guess is that Github just recognizes and supports previewing this particular spec.

75 Blog Posts to Learn Data Visualization
This tutorial will show you how to convert publicly available shapefiles to TopoJSON to create interactive maps with d3/d3-geo. I will show you how to do this without the use of the command line so you can get into experimenting with d3 as fast as possible. If you are interested in working with shapefiles and TopoJSON in a more advanced fashion, I suggest you take a look at Mike Bostockās recent multipart tutorials on command-line cartography.

Maps with D3 and Svelte
The next chart in the series is a simple map of the world. In this chart Curran actually uses a Topojson file, then converts it into Geojson and then plots it. I am not planning to do that as it seems complicated and also for some reason the topojson library does not play nice with Node on my computer and I was too lazy to actually debug it š¬. So instead I are going to use a simple geojson I found on D3 Graph Gallery.

I built a full stack website where you guess the country based on its music!
For the globe spinning, I used d3 and topojson to render the world at whatever projection/rotation/etc I give it. Then, using requestAnimationFrame, every frame I slightly rotate the world. Then the "water" behind it is just a blue circle that has hidden overflow.

[OC] The Hague Schematic Tram Map Compared to the Geographic Map
Using a d3-geo we make projection and a path generator to 'draw' the geographic lines

My lockdown side project: An interactive vintage map builder
Thanks for the compliments! The territory data is coming from https://github.com/aourednik/historical-basemaps, I use this data to render an SVG map with D3.js. This is pretty powerful since you can control every part of the rendering mechanism. With D3-geo you can easily do the projections and graticule.
