{"version":"1.0","type":"rich","title":"FMouse follower","description":"A single gray circle tracks the user's mouse in real time, filling the browser window with an interactive SVG canvas. The React application uses the `useState` and `useCallback` hooks to manage and update the mouse's screen coordinates on every `mousemove` event, rendering the circle's `cx` and `cy` attributes accordingly. Built with React 16.9 and ReactDOM, the example demonstrates a minimal state-driven visualization loop without any external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef84eafcc6c24d2ebe2cb6119fa53253?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
