{"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 constructing a smiley face from SVG shapes. The code uses `d3.select` and `d3.append` to create concentric circles for the face and eyes, alongside SVG `rect` elements for the eyebrows. The eyebrows animate using chained `transition().duration()` calls, moving them up and down over two-second intervals. A mouth is drawn as a path using the `d3.arc` generator with specified inner and outer radii and angular range. The visualization runs as a self-contained HTML page with an embedded YouTube video for reference.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09425047fe7d44e7bd0b1e98c5c1ee39?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
