{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered in SVG demonstrates fundamental D3.js DOM manipulation. The face uses D3 selections to append a yellow circle, eyes, and a mouth via the `arc()` shape generator. With `transition().duration()`, the eyebrows animate upward and back, moving a group containing two rectangles. The code imports `select` and `arc` from the d3 module, targeting an SVG element sized through its attributes. Data is hardcoded as numeric constants for geometry, with no external dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/161e6a2d5347410d9f43178ba4d851fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
