{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face rendered in SVG follows the mouse cursor across a yellow background. The face, built from React components for the background circle, eyes, and a d3.arc-generated mouth, updates its position via React state on every mousemove event. The visualization uses React’s useCallback and useState hooks to track client coordinates, re-rendering the face container at the new location.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b4326292ab4433cbe402258d4c50bc1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
