{"version":"1.0","type":"rich","title":"d3 Starter smiley face","description":"This example shows a simple animated smiley face built with D3.js v5 and rendered as SVG. The face consists of a yellow circle with eyes, eyebrows, and a mouth drawn using SVG shapes and an arc path. The eyebrows animate up and down via chained `transition().duration()` calls, creating a winking or expressive effect. The code uses D3's `select` and `arc` APIs, along with SVG attributes and transforms, to position and style each element relative to the center of the canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/77b959f1abce4120b4dd5e1ef01cdb3e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
