{"version":"1.0","type":"rich","title":"FCC: Smiley w/ React components","description":"A grid of eighteen randomly generated smiley faces, each built from React components and rendered as SVG, demonstrates how to compose and reuse visual elements programmatically. The `Face` component assembles a yellow `BackgroundCircle`, two `Eyes` circles, and a `Mouth` path created with the `d3.arc()` API for a curved smile. Each face’s dimensions—stroke width, eye offset and radius, and mouth properties—are randomized via `Math.random()` within the `App` component, producing unique variations across the grid while maintaining consistent facial structure. The example uses React’s `StrictMode` and `ReactDOM.render` to manage the SVG output, with D3 v6 providing the arc geometry for the mouth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3327d5a74d84f8688412c5cd5dbacf9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
