{"version":"1.0","type":"rich","title":"D3 Face","description":"A smiling face rendered in SVG animates its mouth and eyelids using D3 transitions. The code draws a yellow circle for the head, positions two eyes, and constructs an arc-based mouth with `d3.arc()`. The mouth transitions between two arc radii over two seconds, while rectangular eyelids move up and down using chained `.transition().duration()` calls. Built with D3 v5 selections, the example demonstrates SVG shape manipulation and timed animations within a React-free HTML page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81b55f972c3349fc8181fe7ab6f754dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
