jasonlong/isometric-contributions

This is a browser extension for Chrome, Brave, Firefox, and Microsoft Edge that transforms the contribution graph on your GitHub profile page into a 3D isometric pixel art view. The standard GitHub contribution graph is a flat grid where darker squares represent days with more activity. This extension adds a button to toggle between that familiar 2D view and a version where each day becomes a column, with taller columns for days when you contributed more. The author notes it is more of a visual novelty than a practical improvement. The 3D view makes it easier to see how much higher-activity days stand out compared to quieter ones, but it loses some useful features in exchange: there are no date labels, you cannot hover a column to see the exact count, and tall columns can block shorter ones behind them. Installing it is straightforward through the official extension stores for each browser. Developers who want to modify it can load it manually in Chrome by enabling developer mode in the browser's extensions settings and pointing it at the source folder. The project uses a small open-source library called obelisk.js to draw the isometric shapes on a canvas element overlaid on the page. The author has stated they are not currently planning to add new features, so anyone wanting to submit changes with new functionality should reach out first before writing code.
