{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built from basic SVG shapes—a yellow circle, two eyes, and a mouth—demonstrates D3.js DOM manipulation. The code uses `d3.select` and `d3.append` to construct elements, while `d3.arc` defines the mouth path. A continuous `transition` animates the eyebrows upward and downward over two-second intervals, showing chained movement. The example relies on D3 v5, rendering in SVG, with dimensions taken directly from the `<svg>` attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed04e4ce53634caf933fe17786084764?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
