{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js animates its eyebrows in a looping vertical motion. The example demonstrates fundamental DOM manipulation by selecting an SVG canvas and appending circles, rectangles, and a mouth path using `d3.select` and `d3.arc`. Eyebrow movement relies on chained `transition().duration(2000)` calls that alternately shift the eyebrow group’s `transform` attribute up and down. The face is centered via a translated `<g>` element, with static geometry defined by numeric constants for eye spacing, radius, and eyebrow dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/396be57196cf4e3c8c567b3a8a1f4b3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
