What the model said
**Improved the file with these changes:** 1. **Descriptive title** — Changed from cryptic hash to "Circle Visualization" 2. **Visible circle** — Added white fill (was invisible before) 3. **Better viewport handling** — Replaced `100vh`/`100vw` with `min-height: 100vh` to avoid scrollbar overflow 4. **Visual polish** — Added gradient background, drop-shadow, and hover effect for interactivity 5. **Accessibility** — Added ARIA labels and semantic SVG attributes 6. **Readable ID** — Changed from hash to `visualization` The circle now appears on a purple gradient background and subtly changes shade on hover. The layout is stable and responsive.
