A vanilla JS web app that visualizes any GitHub profile with heatmaps, commit charts, repo lists, and language pies using the REST API.

Grab GitHub API token (optional), Chart.js, vanilla JS; fetch user/repos/events, transform data, render with Canvas/SVG or grids.

Totally—open source, fork away, no paywalls.
