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 it’s topology extension TopoJSON. Creating interactive maps could not have been simpler.

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 Bostock’s 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 😬. 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.

Observable 2.0, a static site generator for data apps
Yep, Evidence is doing good work. We were most directly inspired by VitePress; we spent months rewriting both D3’s docs (https://d3js.org) and Observable Plot’s docs (https://observablehq.com/plot) in VitePress, and absolutely loved the experience. But we wanted a tool focused on data apps, dashboards, reports — observability and business intelligence use cases rather than documentation. Compared to Evidence, I’d say we’re trying to target data app developers more than data analysts; we offer a lot of power and expressiveness, and emphasize custom visualizations and interaction (leaning on Observable Plot or D3), as well as polyglot programming with data loaders written in any language (Python, R, not just SQL).

Animated map showing frequency and location of births around the world [OC]
I made this interactive visualization that attempts to show the real-time frequency and location of births around the world. A country’s annual births (i.e. the country’s population times its birthrate) were distributed across all of the populated locations in each country, weighted by the population distribution (i.e. more populated areas got a greater fraction of the births). Data Sources and Tools Population and birthrate data for 2023 was obtained from Wikipedia (Population and birth rates). Population distribution across the globe was obtained from Socioeconomic Data and Applications Center (sedac) at Columbia University. Data is processed and visualized at a 1 degree x 1 degree resolution, each of which has a different probability of a birth occurring in a specific time period. D3.js was used to create the map elements and html, css and javascript were used to create the user interface.

How do you implement library types?
When I go to the homepage of types/d3 the only hint for any kind of documentation is what seems to be the main github page of d3. It's highly possible I'm missing something here, so sorry if I am but I can't find any documentation of how you are supposed to type these library objects.
