{"version":"1.0","type":"rich","title":"Start with D3.js","description":"This visualization creates a simple smiley face using D3.js selection and shape-generation methods. The code renders a yellow circle as the face, two black circles for eyes, and an arc path for the mouth, centered within an SVG using translation. It demonstrates `d3.select`, `arc`, and SVG attribute manipulation via `attr()`. The example is a minimal starter project that runs with D3 v6 and includes a plain HTML page with separate CSS and JavaScript files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
