{"version":"1.0","type":"rich","title":"D3.js Starter","description":"This example shows a simple smiley face drawn with D3.js, using a yellow circle for the head, two black circles for eyes, and an arc path for the mouth. It renders to an SVG element with fixed dimensions. The code imports `select` and `arc` from D3 v5, uses `svg.append` to create each shape, and sets attributes like `fill`, `r`, and `cx`/`cy` directly. The mouth’s path is generated by the `arc()` function with specified start and end angles. The page loads D3 from a CDN and runs the script in a React-based setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d7423073ee54ee1ac8fafb3e4abda5c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
