{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example shows a yellow smiley face built with SVG elements in D3.js, whose eyebrows animate upward and downward in a looping transition. The code constructs the face using simple shapes: `circle` for the head and eyes, `rect` for the eyebrows, and a `path` generated with the `d3.arc` function for the mouth. D3 selections and the `transition().duration()` method drive the eyebrow movement, while the SVG is centered within a fixed 960×500 viewport using a translated `<g>` container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec65dd4936a54c26b3537a1926f174f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
