web heatmap visualization
pa7/heatmap.js is a JavaScript library for drawing canvas-based heatmaps for the web, often used for density visualization on maps.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
same job, different approach: a modern TypeScript heatmap library, but not a drop-in peer for canvas density maps.
🌞 A highly customizable JavaScript library for generating interactive heatmaps. It transforms data into smooth, visually intuitive heat layers, making patterns and intensity easy to spot at a glance.
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
choose for a minimal, dependency-free canvas heatmap, but it's unmaintained for 2+ years.

an older pixel-based canvas heatmap library, only if you need a simple renderer and accept 4+ years unmaintained.
Pixel based heatmap with html5 canvas.
choose only if you need WebGL-based heatmaps and can accept an 11-year-old unmaintained library.

These projects were analysed and named heatmap.js among their alternatives. The relationship is not symmetric — how heatmap.js rates them is a separate judgement, made when heatmap.js is analysed in its own right.
calls heatmap.js “Choose for simple canvas heatmaps when you need only that, but it is narrow and unmaintained.”
📱📈An elegant, interactive and flexible charting library for mobile.
calls heatmap.js “when you specifically need canvas-based heatmap overlays, but not general dashboard charts.”
