My project localizes the audience of any GitHub user on a map, whether it s followers or following. It is written in TypeScript and is totally client side, it s built with React and D3 for the world map. I ve made some updates and now you can just enter any gitHub user without necessarily putting in your PAT. It uses graphql to fetch all data first, but I ve noticed some followings are missing (it s a bug on the GitHub API), so I recheck and recover the missing data by coupling the fetching with the github rest api and reconciling them after. I also wrote a custom geocoder to parse the location into a country (it s not perfect yet, but it has a high success rate so far).
