{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"This example builds a simple smiling face using D3.js SVG primitives, starting with a yellow circle for the head, two circles for eyes, and an arc path for the mouth. A group of rectangular eyebrows transitions upward and back down over two seconds using chained `transition().duration(2000)` calls, creating a subtle animation. The face is centered by translating a parent `<g>` element to the SVG’s midpoint, with all positioning handled via explicit `attr` values for coordinates and dimensions. The implementation relies on D3’s `select`, `arc` generator, and transition API, rendering entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7dbcff6437b474abbbb1ee37cc933c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
