{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face is drawn with SVG shapes, with its eyebrows animating up and down in a repeating loop. The example demonstrates fundamental DOM manipulation in D3.js v5, using `select` and `append` to build circles, rectangles, and a path. The mouth is created with the `d3.arc` API, and the eyebrow motion relies on chained `transition().duration()` calls to alternate the transform attribute, creating a simple, continuous facial animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ef2071e6ae84898b49b8f554f986bc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
