{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from SVG primitives, including circles, rectangles, and an arc-based mouth. The face’s eyebrows animate upward and downward using chained `transition().duration()` calls on a group element’s `attr('transform')`. Code imports `select` and `arc` from the D3 v5 module, explicitly setting the SVG’s background color to red. All elements are positioned relative to a centered group, illustrating coordinate transforms and append/attr operations without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7179de066b9649de9fefe2753ffbc843?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
