{"version":"1.0","type":"rich","title":"Let's make face with D3","description":"This example draws a simple cartoon face using D3.js v6, rendered as SVG elements with a short animation. It shows a yellow circle as the head, two black circles for eyes, and an arc-based mouth that transitions from a filled semicircle to a hollow crescent shape over two seconds. The code uses D3 selections, the `arc` generator for the mouth path, and a chained `transition().duration()` to animate the shape change. The face is centered within a 960×500 SVG canvas, with hardcoded positions for facial features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93e01fecafba4a7c9a2eed8a6caa356d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
