{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered as SVG elements animates its eyebrows in a continuous loop. The example demonstrates fundamental D3.js DOM manipulation by selecting an SVG canvas, appending a centered group, and building the face from circles, rectangles, and an arc path. Eyebrows transition vertically using chained `transition().duration()` calls, moving down 50 pixels then returning. The code imports `select` and `arc` from D3 v5, constructing the mouth with the arc generator’s inner and outer radii and angle parameters.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ad6e169977f4e0cb6dfbc44348ee179?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
