{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle with a black outline follows the mouse cursor across an SVG canvas. Built with React and D3 v6, the app tracks the pointer's `clientX` and `clientY` coordinates on a `mousemove` event, updating the circle's `cx` and `cy` properties via React state. The `BackgroundCircle` component renders the static yellow circle, while the main `App` component manages the interactive position updates. The visualization demonstrates real-time data binding between user input and SVG element attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17e06339a2cb4a579963fc795443b87c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
