{"version":"1.0","type":"rich","title":"Face Smiling","description":"A smiley face drawn with SVG shapes animates its eyebrows upward and back down over four seconds. The code uses D3 v5 selections and transitions to move a group containing arc and rect elements, while the face itself is built from circles and a path generated with the d3.arc function. The example demonstrates fundamental DOM manipulation in plain JavaScript, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c62ebc70696347f7a21adcac9fdf92e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
