{"version":"1.0","type":"rich","title":"Learn D3.js","description":"This visualization draws a smiling face using D3.js in an SVG canvas. A yellow circle forms the head, with black circles as eyes and a curved arc path as the mouth. The eyebrows, rendered as rectangles, animate upward and then back down using chained `transition().duration(2000)` calls. The code uses the `select`, `append`, and `arc` APIs from D3 v7 within a React framework, manipulating SVG attributes directly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6523724cead247aa9f9d99ad47fb9edb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
