{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face whose eyebrows animate up and down. The code uses `d3.select` to target an SVG element, `svg.append` to construct geometric shapes like rectangles and arcs, and `transition().duration()` to create a looping eyebrow movement over two seconds. The face is rendered as a static SVG with a semi-transparent green rectangle, red-stroked eyes, and a mouth drawn via the `d3.arc` shape generator, all centered using SVG group transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edd144cca7fc47c2a2534d7985d406e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
