{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with moving eyebrows demonstrates basic D3.js DOM manipulation. The code uses D3 v5’s `select` and `arc` to draw SVG circles, rectangles, and a mouth path on a fixed 960×500 canvas. Eyebrow rectangles transition upward and back down over two seconds via chained `transition().duration(2000)` calls. The face is centered using an SVG `g` group with transformations, while eye and eyebrow positions are calculated from fixed numeric offsets. No external data is loaded; all shapes are generated programmatically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/778e7a166abb4705b3e15c5772380ead?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
