{"version":"1.0","type":"rich","title":"Hello VizHub","description":"A cheerful yellow smiley face is drawn in an SVG canvas using D3 v5, with black outlined eyes and a mouth. The example demonstrates basic SVG shape creation and manipulation through D3’s `select` and `append` methods. Two rectangular eyebrows animate vertically using `transition().duration()`, moving up and then back down over two seconds each. The code also utilizes D3’s `arc` path generator to construct the mouth, showing fundamental drawing and animation capabilities on a static 900x600 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/42a7203f6ffc4d72bbd71ddbd3afee3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
