{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A yellow circle follows the mouse cursor across a blank SVG canvas. The visualization uses React with hooks, specifically `useState` and `useCallback`, to track mouse coordinates from an `onMouseMove` event listener on the SVG element. The circle’s center position updates dynamically via React state, rendering through `ReactDOM` in a fixed 960×500 viewport. No external data source is used; the interaction is driven entirely by local pointer events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a03764e931f43e8853ab65fd4145b00?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
