{"version":"1.0","type":"rich","title":"d3 visualization","description":"This example uses D3 v5 to draw a smiling face as an SVG graphic, composed of a yellow circle, two eyes, eyebrows, and an arc-based mouth. The eyebrows animate vertically using chained `transition()` calls, moving up and down over two-second durations. The code builds the visualization by selecting the SVG element, calculating its center from width and height attributes, and positioning grouped elements with `translate` transforms. It uses D3's `arc` generator for the mouth path and relies on SVG primitives like `circle` and `rect` for the other features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a082bc327b1d45d9809c5bf928c39362?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
