{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing a static smiley face from SVG shapes, including a yellow circle head, eyes, eyebrows, and an arc-based mouth. The eyebrows animate upward and downward through chained `transition()` calls that modify their group’s `transform` attribute over two-second intervals. The code uses D3 selections, `arc()` for the mouth path, and SVG attributes like `cx`, `r`, and `width` to position elements. All shapes are appended to a centered `<g>` group inside an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db4576634e4b40bea563dd8b3d55d9cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
