{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js demonstrates basic SVG shape creation and animated DOM manipulation. The face consists of yellow circle for the head, two eyes, a mouth drawn with `d3.arc`, and rectangular eyebrows that move up and down using chained `transition().duration()` calls. The code uses D3 v5 selections, `append`, and attribute setters to construct the static elements, while the eyebrow animation shows how transitions can alter the `transform` attribute over time. This example highlights fundamental data-driven document manipulation without any external dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/400b45ba15fb44b48fcf7abf3080af6e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
