What does the GitHub Activity Visualizer do?

It pulls GitHub API data for any username, rendering profile cards, repo lists with stars/forks/languages, commit charts, and contribution heatmaps — all interactive, no login needed.

How to build a similar GitHub dashboard ?

Grab GitHub REST API token (optional for rate limits), use fetch() for data, Chart.js for graphs, CSS Grid for layout. Handle pagination on repos/commits; visualize with D3 or Canvas for custom heatmaps.

Is vanilla JS enough for portfolio projects?

Absolutely — recruiters value clean code over frameworks. This 200KB app outperforms many React demos; focus on API smarts, responsive design, edge cases.
