{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow smiley face, built from SVG circles and an arc, tracks the cursor across a full-screen canvas. The face renders with React components, including a d3.arc-generated mouth, while the center position updates via React state on mouse events. The app uses React's useCallback and useState hooks to manage the mouse coordinates, drawing the face inside a transparent SVG that spans the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a0b5f9b1a5e443f9bc9ffa441557a8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
