{"version":"1.0","type":"rich","title":"Let's make a Smiley","description":"This example shows a stylized smiley face built with D3.js that animates its eyebrows up and down. The face is constructed from SVG shapes: a yellow circle for the head, two dark circles for eyes, and a path generated with the `arc` function for the mouth. The eyebrows are rectangles that move via chained `transition().duration(2000)`, shifting vertically to create a playful expression. D3 v5 selections and attribute methods are used throughout, with the entire figure centered in a green-background SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7955d0f132e480984e00b01837e8bc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
