{"version":"1.0","type":"rich","title":"Mouse Buddy","description":"A single gray circle tracks the mouse cursor in real time within an SVG canvas. The visualization shows how React state updates can drive direct SVG element positioning. The `App` component captures mouse coordinates via the SVG `onMouseMove` handler, stores them with `useState`, and re-renders the circle’s `cx` and `cy` attributes on every movement. Built with React 18 and D3 v7, the example renders purely through SVG elements without additional data sources or animation logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d716644622aa496b9185dbc359b28bf3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
