{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse pointer across a blank SVG canvas. The example demonstrates interactive state management in React, where mouse coordinates update the circle’s position in real time. It uses React’s `useState` and `useCallback` hooks to track and handle mouse movement events, while d3.v5 provides the SVG rendering utilities. The circle’s center is set directly from the `clientX` and `clientY` properties of the browser’s mouse event, with no additional data or animation logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a23916adb8624d31a31cd45ad22fcf08?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
