{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single blue circle tracks the mouse position within an SVG canvas. The visualization demonstrates how React state updates can drive SVG element positioning in real time. The code uses React's `useState` and `useCallback` hooks within a functional component to capture `clientX` and `clientY` coordinates from the SVG's `onMouseMove` event, updating the circle's `cx` and `cy` attributes. D3 v7 is loaded but only for its `arc` function, which is unused in the final rendering. The example renders purely with React and SVG, with no external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60c323a0470b4933ac36a1ca57d003d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
