{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiling face in SVG using D3.js v5, showing fundamental DOM manipulation with selections and SVG shape elements. It draws a yellow circle for the head, two eyes, eyebrows as rectangles, and a mouth created with `d3.arc()`. The animation uses `transition().duration()` to move the eyebrow group up and down repeatedly, demonstrating chained transitions over a two-second interval. The page is set up with a simple HTML structure and imports D3 via a CDN, with all elements positioned relative to the SVG center.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb7fca0de1764ef0bf6ae0d295e4e15f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
