{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example shows a simple animated smiley face drawn in an SVG canvas using D3.js. The face consists of a yellow circle, two eyes, eyebrows, and a mouth shape. It demonstrates core DOM manipulation with `d3.select` and `svg.append`, applying attributes like `attr('r')`, `attr('cx')`, and path building via `d3.arc`. The eyebrows animate through chained `transition().duration(2000)` calls, moving them down and back up over four seconds. The code uses D3 v6 and explicitly sets the SVG background to red via `svg.style`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c91fe78737a452d875d24b5320f39ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
