{"version":"1.0","type":"rich","title":"Smile face using D3.js","description":"This example builds a smiling face with SVG shapes using D3.js v5. It draws a yellow circle for the head, two black circles for the eyes, and an arc-generated mouth using the `arc()` function. Animated eyebrow rectangles transition vertically via `transition.attr`, moving them up and down repeatedly. The face is centered with a group transformation, and all shapes are styled with fill and stroke attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9114bc22660f41bb8249b02d2d359161?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
