{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single dark circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management and event handling within a data-visualization context. Using the `useState` hook, the `App` component tracks mouse coordinates via an `onMouseMove` event on the SVG element, then re-renders the circle's `cx` and `cy` attributes. It relies on React 17, ReactDOM, and D3 v6 for the SVG rendering, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
