{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"This example shows a smiley face drawn with SVG primitives in D3.js v5, featuring a randomly colored face, fixed eyes, and a curved mouth. It demonstrates fundamental DOM manipulation by appending circles and a path directly to an SVG container. A button triggers a color change, using `transition().duration(500).attr('fill', ...)` to animate the face’s fill to a new random HSL value generated by `getRandomColor()`. The code relies on D3’s selection and transition APIs without any external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cdcc9db3e2884db288a697dca849c33d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
