{"version":"1.0","type":"rich","title":"Mouse","description":"A single black circle follows the mouse cursor across an SVG canvas, with its position updating reactively in real time. The circle’s center is driven by the `clientX` and `clientY` coordinates from the SVG element’s `onMouseMove` event, stored in React state via `useState` and `useCallback`. The visualization uses React 17 for rendering, D3 v7 for SVG utilities, and demonstrates a simple interactive pattern without any data source or external dataset. The circle radius is fixed at 30 pixels, and the SVG viewport is 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53f9014b6b9944108878cdc046dcc632?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
