{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example demonstrates a minimal D3.js visualization embedded in an HTML page, rendering a single red circle with a dark red stroke as a simple \"smiley face.\" The code uses `d3.append` to create SVG elements within an `<svg>` tag, with styling controlled via CSS attributes like `fill` and `stroke-width`. The circle is added to a group (`gSmile`) using D3’s selection API, though the `transform` method call is incomplete. The page imports D3 v5 from a CDN and uses a React-compatible setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f919bf80de174ffba6d0aaa94fbfc1e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
