Mandelbrot explorer · qwen3-coder

I'll create a self-contained HTML file that renders the Mandelbrot set with smooth color gradients, panning, and zooming capabilities.

I've created a complete Mandelbrot set explorer in a single HTML file with the following features: 1. Full-screen canvas that resizes with the window 2. Smooth color gradient rendering using HSL color mapping 3. Click-and-drag panning functionality 4. Mouse wheel zooming with fixed-point zooming (zooms toward cursor position) 5. Automatic iteration count adjustment for better detail when zooming 6. Reset view by clicking anywhere 7. Responsive design that works on any screen size The implementation uses smooth coloring techniques to create beautiful gradient transitions and handles complex number calculations efficiently. The interface provides intuitive navigation with visual feedback (cursor changes during dragging). To use the explorer: - Drag to pan around the Mandelbrot set - Scroll to zoom in/out (zooms toward your cursor position) - Click anywhere to reset to the initial view - The view automatically adjusts detail level based on zoom The fractal is rendered using the classic Mandelbrot iteration algorithm with smooth coloring for beautiful gradients. The color scheme transitions from deep blues through purples to yellows as iteration counts increase.
