{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js v5 by constructing a smiley face out of basic SVG shapes. The code uses `d3.select`, `d3.append`, and chained `.attr()` calls to create a yellow circle, two eye circles, a mouth path drawn with `d3.arc()`, and a rectangular eyebrow that animates vertically via a pair of `transition().duration()` calls, moving down and back up repeatedly. No external data is used; the visualization relies purely on hardcoded geometry and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f23e625de89044589975cd8c495b7f41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
