{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with SVG is animated so its eyebrows move, demonstrating fundamental DOM manipulation in D3.js. The example uses a linear color scale with `d3.interpolateHcl` for the gradient background and D3’s selection methods to bind and update elements. The code also loads a hierarchy dataset and applies `d3.pack` for circular packing, though the visible rendering focuses on the animated face. Rendering is SVG-based with transitions, shown via a video and live code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d6ad968f3774b94a458c89d1c6fd5b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
