{"version":"1.0","type":"rich","title":"Dataviz 2018 - 2. D3 starter, SVG DOM manipulation, transition(animation), Smile Face - Ep4","description":"This example shows a yellow smiley face built from SVG elements, with animated eyebrows that move up and down in a looping transition. The code creates a circle for the face, two circles for eyes, a mouth drawn with `d3.arc`, and rectangles for eyebrows using D3 selections. It demonstrates SVG DOM manipulation by appending elements to groups, and animates the eyebrow group’s `transform` attribute with chained `transition().duration()` calls. The visualization runs in D3 v7 and renders to a 960×500 SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a5a391d9b814bbd894711c933426447?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
