{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates how D3.js can animate a smiley face by manipulating SVG shapes, specifically moving its eyebrows up and down over a four-second loop. The code builds the face using `d3.select` to append SVG elements like circles, rectangles, and a path for the mouth, with an arc generator defining the mouth’s curve. The eyebrows use chained `transition().duration(2000)` calls to shift their vertical position, creating the facial animation. The entire face is centered within an SVG canvas using a `<g>` element, with hardcoded layout constants for eye spacing and dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/476497128025445f8ca931abbd4762cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
