{"version":"1.0","type":"rich","title":"Smile face II","description":"A smiley face is rendered as a single SVG circle that follows the mouse cursor across a 960-by-500 viewport. The circle’s center coordinates update on every mouse movement via React state and the `onMouseMove` event handler. The example uses React 16.9 and D3 v7’s `arc` import (though unused), with SVG rendering managed by ReactDOM. The circle starts at the center and tracks the pointer’s client coordinates in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6db904d781d74e139df43bb82fd960e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
