Render the Mandelbrot set with a smooth color gradient on a full-screen canvas, with click-and-drag to pan and mouse-wheel to zoom.
thinking
The user wants a single-page web app that renders the Mandelbrot set with: 1. Full-screen canvas 2. Smooth color gradient 3. Click-and-drag to pan 4. Mouse-wheel to zoom I'll create a complete, self-contained index.html file with all CSS and JS inline, no external resources.
/workspace/index.html (9681 bytes)Successfully wrote 9681 bytes to /workspace/index.html
thinking
The file has been written successfully. Let me verify it's there and provide a summary to the user.
{"command":"wc -l /workspace/index.html && file /workspace/index.html"}309 /workspace/index.html /bin/bash: line 1: file: command not found Command exited with code 127
thinking
The file is 309 lines and exists. Let me give the user a summary of what was built.
Done — `/workspace/index.html` is ready (309 lines, fully self-contained, zero external dependencies). **Features:** - **Full-screen Mandelbrot rendering** via `ImageData` for pixel-level speed - **Smooth (continuous) coloring** using the normalized iteration count formula with a 4096-entry cosine-gradient palette - **Click-and-drag to pan** — moves the viewport freely - **Mouse-wheel to zoom** — zooms toward cursor position - **Touch support** — single-finger drag to pan, pinch to zoom - **`R` key** resets to the default view - **Live info overlay** showing current center coordinates and zoom level
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
