{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face is rendered as a yellow circle with black eyes, animated eyebrows, and a curved mouth built from an arc path. The code uses D3 v5 selections to append SVG shapes, and chains `transition().duration()` calls to move the rectangular eyebrows up and down. The mouth is generated with the `d3.arc()` helper, specifying inner and outer radii and angular extents. Static circle elements define the face and eyes, while the animation runs once on load in a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9396ce966fa45918aa9eaccc5f26e76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
