Vertex Dot Radar: A single series polar chart that pins a solid dot on every axis corner so each measured value reads as a point rather than only as a silhouette.

## Frameworks

react, vue, svelte, astro, html

## Preview controls

These controls are passed to the demo. Defaults and limits describe the preview; consult the implementation for its full prop API.

| Name | Type | Default | Options or constraints |
| --- | --- | --- | --- |
| accent | color | #38BDF8 | No additional limit in the metadata. |
| dotRadius | number | 4 | From 2 to 8; step 0.5 |
| fillOpacity | number | 0.55 | From 0 to 1; step 0.05 |
| rings | number | 4 | From 2 to 6; step 1 |
| showLabels | boolean | true | No additional limit in the metadata. |

## Usage notes

Vertex Dot Radar uses the card preview frame with a light/dark theme setting.

### Which frameworks are available for Vertex Dot Radar?

Vertex Dot Radar is available for React, Vue, Svelte, Astro, HTML. The live preview uses React; the source observations below apply to index.tsx. Check the selected port before relying on the same interactions.

### What does Vertex Dot Radar depend on?

The React metadata lists these npm dependencies beyond React: motion.

### What accessibility details are visible in Vertex Dot Radar?

The React source for Vertex Dot Radar includes: attributes and handlers (aria-hidden, aria-label, onKeyDown, tabIndex); explicit roles (group, img); key comparisons (ArrowDown, ArrowLeft, ArrowRight, ArrowUp). These are source observations. Verify accessible names, focus order and keyboard behavior in the composed page.

### How does Vertex Dot Radar handle reduced motion?

Vertex Dot Radar reads the motion preference in its React source through useReducedMotion(). Preference-dependent expressions in index.tsx: reduce ? false : \{ d: collapsedPath, opacity: 0 \}; reduce ? \{ cx: p.x, cy: p.y, scale: 1 \} : \{ cx: CENTER, cy: CENTER, scale: 0 \}; scale: reduce ? \{ duration: 0 \} : \{ type: "spring", stiffness: entered ? 380 : 420, damping: entered ? 22 : 13, delay: entered ? 0 : 0.55 + i \* 0.05 \}. Check the full implementation, shared styles and selected port with reduced motion enabled; these observations do not establish that every animation stops.

## Install through MCP
