{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example shows a yellow smiley face built with SVG shapes whose eyebrows animate upward and downward in a looping motion. The code demonstrates fundamental D3.js DOM manipulation by selecting the SVG canvas, appending groups for positioning, and constructing circles, rectangles, and an arc-based mouth using `d3.select`, `d3.arc`, and chained `transition().duration()` calls. The face is centered via a translated group, with all coordinates calculated relative to the viewport dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f6179ea88ed411bb4837f95d224c8d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
