Hi HN, I've always wondered how to transform public GitHub profile data into something more tangible and understandable at a glance like follower locations. So I decided to build a web tool using D3. I chose React for rendering, built a custom TypeScript geocoder to map raw user locations to ISO country codes, and let D3 handle the map projection and svg generation.
