{"version":"1.0","type":"rich","title":"D3 Smiley Face Part + React","description":"A D3 smiley face built as a React component renders a yellow circle with black stroke, two eye circles, and an arc-shaped mouth using the `arc()` generator from d3-shape. The SVG is sized to the browser window, with the face centered via a `<g>` transform. `ReactDOM.render` mounts the app, while the background circle, eyes, and mouth use fixed dimensions calculated from `width`, `height`, and radius constants. The mouth’s path is produced by `d3.arc()`, with start and end angles defining the open smile.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3334925f451041f8b5299fddbf85e6fb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
