The user wants me to create an interactive Mandelbrot set visualization with: 1. Full-screen canvas 2. Smooth color gradient 3. Click-and-drag to pan 4. Mouse-wheel to zoom This is a single self-contained HTML file project. Let me create this.

I've created the Mandelbrot set visualization. Let me verify the file was written correctly.

The file is created. It's a self-contained HTML file that renders the Mandelbrot set with: 1. Smooth color gradient using HSL color mapping with continuous iteration values 2. Full-screen canvas 3. Click-and-drag to pan 4. Mouse-wheel to zoom (with zoom centered on mouse position) Let me summarize what was created.
Created `index.html` — a self-contained Mandelbrot set explorer: **Features:** - **Smooth coloring**: Uses fractional iteration values with HSL gradient cycling through the hue spectrum (blue → purple → pink → orange), creating smooth color bands rather than harsh contour lines - **Full-screen canvas**: Automatically fills the viewport - **Pan**: Click and drag anywhere to pan the view - **Zoom**: Mouse wheel zooms toward the cursor position (up to ~3 billion magnification) - **Adaptive iteration**: Max iterations increase as you zoom in for more detail - **Info panel**: Shows real-time center coordinates, zoom level, and iteration count The classic Mandelbrot set equation `z = z² + c` is computed per-pixel. Points that escape quickly get lighter colors; points in the set remain black. The smooth coloring uses `log(log(z))` normalization to eliminate the banded effect.
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.
RUN
EVALUATION
Mandelbrot set renders with smooth color gradient; drag pans and wheel zooms correctly, keyboard inputs have no effect as expected.

MEASUREMENTS
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.
