{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face is drawn on a dark background using SVG shapes, with animated eyebrows that rise and fall over two seconds. The example demonstrates fundamental D3.js v3 DOM manipulation by building the face with `circle` elements, a `rect` for each eyebrow, and a `path` created with the `d3.arc` helper for the mouth. The eyebrows are moved using chained `transition().duration()` calls, which shift the group’s `transform` attribute to create the up-and-down motion. All shapes are centered within an SVG canvas using a translated `<g>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89b6b69305354acabd1a3c36646f34ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
