{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js v5 example creates a smiley face in an SVG, animating its eyebrows through a sequence of transitions. The face is built with a yellow circle for the head, two circles for eyes, and a crescent-shaped path for a mouth, all grouped and transformed to center on the canvas. Eyebrows, rendered as rectangles, move up and down over two-second durations using the `transition` API, demonstrating fundamental DOM manipulation with `select` and `append` methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f741f0de7fac4537a1bbfea2b11316b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
