{"version":"1.0","type":"rich","title":"MouseFollower","description":"A smiling face made of SVG circles and an arc follows the cursor across a brown background. The face, composed with React components, updates its position through a mouse-move event handler on an SVG element. The state hook `useState` tracks the cursor coordinates, and `useCallback` memoizes the event handler. The mouth is drawn using `d3.arc()` with specified inner and outer radii, while the eyes and background circle are plain SVG circles. The face translates as a group within an SVG container, responding live to pointer movement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9db30c0342244cddb54d61aa7372db81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
