{"version":"1.0","type":"rich","title":"Hello HTML","description":"This example shows a yellow smiley face drawn with SVG circles and a path, whose eyebrows rise and fall in a looping animation. It demonstrates fundamental DOM manipulation with D3.js by appending SVG elements to a group and using chained `transition().duration()` calls to animate the eyebrow group’s `transform` attribute. The mouth is created using `d3.arc()` with specified inner and outer radii and angle ranges. The code relies on `d3.select` to access the SVG and sets geometric attributes like `cx`, `cy`, and `r` directly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b8f7d3667df40338982a2f330d430ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
