{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with SVG shapes animates its eyebrows in a looping vertical motion. The example demonstrates fundamental D3.js DOM manipulation by chaining `select`, `append`, and `attr` calls to construct circles, rectangles, and an arc-based mouth. Using `d3.arc` for the mouth and `transition().duration()` on a group element, the eyebrows shift up and down over two-second intervals. D3 v5 handles all rendering in an inline SVG, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/337ca0409eb942b7975c033b6206a57f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
