{"version":"1.0","type":"rich","title":"E14 Mouse Follower","description":"A yellow circle follows the mouse cursor across an SVG canvas, moving smoothly as the pointer travels. The example demonstrates interaction with React by using the `useState` hook to store the mouse's x and y coordinates, updating them via the `onMouseMove` event. The `useCallback` hook memoizes the event listener to optimize performance, while `ReactDOM.render` mounts the component. The circle's position is bound directly to the state, leveraging unidirectional data flow to keep the visualization in sync with user input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
