{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face composed of SVG shapes animates on a yellow circular head, with eyebrows that raise and lower repeatedly. The example demonstrates D3.js v5 selections and transitions, using `append`, `attr`, and chained `transition().duration()` calls to animate rectangles. It builds the face with primitive shapes: a circle for the head, ellipses for eyes, a path generated by the `d3.arc` function for the mouth, and animated rects for eyebrows.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98679183b2ed4b348cc610bd6a12c347?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
