{"version":"1.0","type":"rich","title":"let's animate the face ","description":"A yellow smiley face is drawn as an SVG circle with eyes, eyebrows, and a mouth, all positioned using D3.js selections and attribute helpers. The eyebrows and mouth animate via chained `transition.attr` calls, moving vertically and scaling over two-second intervals, demonstrating fundamental DOM manipulation with `d3.select`, `d3.arc`, and transition methods. The example uses D3 v5 and renders entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10e3897d676345bf87ed8ecbef431a41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
