{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A fork of Smiley Face Part II shows a single unfilled circle following the mouse cursor across an SVG canvas. The circle's position updates in real-time based on the pointer's client coordinates. Implemented with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to manage and update the mouse position state, while the SVG `<circle>` element renders the shape. The HTML loads React and D3 from CDN, and the code runs within a React component rendered to the root div.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/063c409958784746a03d6e5530554f74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
