star-history-chart

Add a self-hosted "Stargazers over time" chart to any GitHub repo's README. GitHub now restricts the stargazers endpoint to a repo's own admins/collaborators, so third-party live services (star-history free tier, starchart.cc) return "Requires authentication" for everyone. This generates a static, theme-aware SVG in-repo and auto-refreshes it weekly with a GitHub Action using the repo's own GITHUB_TOKEN. Use when the star chart in a README is broken, shows "Requires authentication", or you want a star history that never breaks.

# Star History Chart (self-hosted, never breaks)

Add a "Stargazers over time" chart that renders from a static SVG committed to
the repo and refreshes itself weekly — no external chart service, no broken
images.

## Why this exists

GitHub now restricts the `/stargazers` endpoint to a repository's own admins and
collaborators. Unauthenticated requests return `{"message":"Requires
authentication"}`, which breaks every third-party live-chart service
(star-history.com free tier, starchart.cc, etc.) for **all** repos. The only
reliable fix is to generate the chart yourself with an authenticated token and
commit a static image. Inside GitHub Actions, the repo's own `GITHUB_TOKEN` can
