{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow SVG smiley face with black stroke is centered on a red background, drawn using D3.js v5 primitives like `circle`, `rect`, and `path`. Animate the face by applying a chained `transition().duration(2000)` to the eyebrows group, moving it vertically up and down. The mouth is formed with D3's `arc()` generator, specifying inner and outer radii and a start and end angle. The example demonstrates fundamental DOM selection and manipulation via `d3.select` and `svg.append`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd702760a6eb4c56b84dd6e8caf3ec14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
