{"version":"1.0","type":"rich","title":"Mouse Follower - Code Optimization","description":"Two navy and red circles follow the mouse cursor across an SVG canvas, offset horizontally to create a trailing effect. Built with React and rendered as SVG elements, the visualization uses the `useState` hook to track mouse coordinates and the `useCallback` hook to optimize the mousemove event handler, which updates the circle positions via `setMousePosition`. The initial mouse position is centered on the 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
