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.

assistant

The user wants a single-page web app that renders the Mandelbrot set with:
1. Smooth color gradient
2. Full-screen canvas
3. Click-and-drag to pan
4. Mouse-wheel to zoom

I'll create a self-contained index.html file with CSS in a <style> tag and JS in a <script> tag.

→ write /workspace/index.html (9539 bytes)

toolResult

Successfully wrote 9539 bytes to /workspace/index.html

The file has been created. Let me verify it exists and check the content.

→ bash {"command":"ls -la /workspace/index.html"}

The file is created successfully. The Mandelbrot set explorer is ready with:
- Full-screen canvas
- Smooth color gradient using sine-wave palette with smooth iteration coloring
- Click-and-drag to pan
- Mouse wheel to zoom (centered on cursor)
- Touch support for mobile (drag to pan, pinch to zoom)
- Keyboard shortcuts: R to reset, +/- to adjust iterations
- Adaptive iteration count based on zoom level
- Real-time info display showing center coordinates, zoom level, and iterations

Done. Created `/workspace/index.html` — a self-contained Mandelbrot explorer with: - **Smooth gradient**: 1024-color sine-wave palette + continuous iteration smoothing (log-log escape time) - **Full-screen canvas** with auto-resize - **Pan**: click-drag (mouse) or single-finger drag (touch) - **Zoom**: mouse wheel (centered on cursor) or pinch gesture (touch) - **Controls**: `R` reset, `+/-` adjust max iterations - **Adaptive iterations**: auto-scales with zoom depth for detail - **Live HUD**: shows center coords, zoom level, iteration count
