Help: D3 Map Data

I am trying to figure out how to make d3 maps. I’m finding it pretty frustrating as the d3 website, docs, and examples, are fairly confusing to me and hard to navigate.

For example, I keep seeing in various tutorials and demos that people are pulling map data files from links that look like this:

but I can’t seem to find where these are listed on the d3 website.
To top it all off, half of the info out there is for d3 version 3 and the other half for version 4.

anyways if anyone could share where to find those json files on the d3 website, or any good tutorials for the d3 map project (the one about plotting meteor impact sites over a world map), that would be super helpful. thanks.
