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).
