{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental D3.js DOM manipulation by building an animated smiley face with moving eyebrows. It renders an SVG scene with a yellow circular head, eyes, and a mouth created using the `d3.arc` path generator. The eyebrows are rectangles that animate upward and downward via chained `transition.attr` calls, moving over two seconds each way. The code uses D3 v5 selections and attributes to construct and position all elements relative to a centered group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f83dfc1d290a42d4a2a2d77c4a882242?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
