{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse cursor within an SVG canvas. The circle’s position updates in real-time based on the pointer’s coordinates, creating a direct and responsive visual link between user input and the rendered graphic. This interaction is built with React using the `useState` hook to track mouse position, which is updated via an `onMouseMove` event handler on the SVG element. The chart is rendered as SVG, leveraging the `d3` library’s `arc` import, though it primarily relies on React’s state management for the dynamic behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
