{"version":"1.0","type":"rich","title":"Smiley Face Part II","description":"This example renders a full-window smiley face using React and D3. It builds the face from SVG primitives: a yellow circle for the head, two black circles for eyes, and an arc path for the mouth. The mouth is generated with the `d3.arc()` API, configured with inner and outer radii plus start and end angles. React manages the component structure and JSX, while D3’s `arc` helper computes the path data. The visualization responds to the browser window size, centering the face and scaling the head radius based on viewport height.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1291c00c8ab44caab8656dc9664dd440?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
