{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"A yellow smiley face rendered with SVG circles and a d3.arc path follows the mouse: a small red circle tracks the cursor across the screen, while the face’s background, eyes, and mouth are positioned around the viewport center. React state updates the cursor-following circle’s coordinates via a mouse move handler, and the d3.arc function in Mouth.js computes the smile path. The example uses React 17, D3 v7, and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/44c6c13536bf4e519819679042671cc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
