{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example renders a simple yellow smiley face using D3.js v5’s `select` and `arc` APIs. The SVG canvas is centered with a `g` transform, then a yellow circle with a black stroke forms the face, followed by two black circles for eyes. A mouth is drawn as a filled arc path using D3’s `arc` generator with specified inner and outer radii and angular extents. The code manipulates SVG attributes directly, with dimensions read from the SVG element itself.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1882fed578846478d4f819492e69481?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
