Code Contributions — Free Calendar Heatmap Template
The Code Contributions template is a GitHub-style calendar heatmap that shades each day of the week by how many commits you made, so heavier coding days appear darker. The sample data tells a familiar developer story: a steady weekday rhythm peaking Wednesday at 12 commits, dipping on Friday and falling away over the weekend (Saturday 3, Sunday 1). It is a ready-made starting point for visualizing coding activity, build streaks, or any daily-count pattern without setting up a heatmap from scratch.
