{"version":"1.0","type":"rich","title":"Intro to D3: Happy Face","description":"A yellow circle face with eyes, eyebrows, and an arc-shaped smile demonstrates fundamental D3.js SVG rendering and animation. The code builds the face using D3 selections and shape generators, including `d3.arc()` for the mouth path, while positioning elements with SVG `transform` attributes derived from the viewport dimensions. Eyebrows animate through chained `transition().duration()` calls, moving them down and then up over four seconds. The example uses D3 v7 within a React project, drawing on a static SVG canvas with no external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/812e84b3e66c4c0fb2ca50ca02b03931?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
