{"version":"1.0","type":"rich","title":"Moving Circle","description":"A simple React component tracks the mouse position and renders a single circle that follows the cursor across an SVG canvas. The circle's center coordinates are updated via React state on every `mousemove` event, using the `useState` and `useCallback` hooks. D3.js v5 is loaded but not actively used, while the rendering relies on React's declarative SVG elements rather than direct DOM manipulation. The example demonstrates basic interactivity and state-driven updates in a React-D3 integration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
