{"version":"1.0","type":"rich","title":"Mouse follower","description":"A yellow circle follows the cursor across an SVG canvas, updating its position in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle with the new `cx` and `cy` attributes. The SVG rendering approach keeps the circle's radius constant at 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4616455d059b4cc3b6cca48a20b77172?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
