{"version":"1.0","type":"rich","title":"Mouse follower","description":"A smiley face rendered as a single SVG circle follows the mouse cursor across a 960×500 canvas. The React component tracks pointer coordinates via an `onMouseMove` handler and updates its position through `useState`, while D3’s `arc` utility is imported but unused. The circle’s `cx` and `cy` attributes are bound directly to the current mouse position, creating a smooth, direct mapping between input and visual output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aef847f73303438d94134a19d2caba32?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
