{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face drawn with D3.js animates its eyebrows in a looping up-and-down motion. The example demonstrates fundamental SVG construction using D3 selections and shape generators, building the face from a yellow circle, two eyes, rectangular eyebrows, and an arc-based mouth. The eyebrows transition vertically via chained `transition().duration()` calls, while `d3.arc` computes the mouth path. The code uses `select` and `arc` from D3 v5, with all elements positioned through SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a307e10277f4c869df137defff7ccf8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
