{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face is drawn entirely with D3.js SVG elements, including a yellow circle for the head, two eyes, and an arc-based mouth. The example demonstrates fundamental DOM manipulation by appending and styling shapes, then animates the eyebrows with a chained `transition().duration()` that moves them up and down. It uses `d3.select` to target the SVG, `d3.arc` to generate the mouth path, and attribute setters like `.attr()` to position each component relative to a centered group. The animation runs once on load, with no user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b5992ac2e615476682c59f26978d30c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
