I've created a single-page web application that renders the Mandelbrot set with smooth coloring, full-screen canvas, and interactive controls for panning and zooming. The app includes: 1. A full-screen canvas that adjusts to window size 2. Smooth color gradient from black to blue to red to yellow based on iteration count 3. Click-and-drag to pan the view 4. Mouse wheel to zoom in/out (with centering on the cursor) 5. Proper handling of the Mandelbrot set algorithm with smooth coloring The implementation uses JavaScript to calculate each pixel's color based on how quickly it diverges in the complex plane, with a smooth gradient effect using fractional iterations. To use this app, simply open index.html in any modern browser. The canvas will automatically fill the entire screen, and you can interact with it by clicking and dragging to pan, or using the mouse wheel to zoom in and out.

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
