{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face drawn with D3.js animates its eyebrows in a looping motion. The example demonstrates fundamental DOM manipulation by building the face from SVG shapes—circles for the eyes, rectangles for the eyebrows, and a path generated with the `d3.arc` function for the mouth. Eyebrow movement is achieved through chained `transition` calls that alternate between two vertical positions over two-second intervals. The code uses `d3.select` to access the SVG and applies attributes via `.attr`, with static geometry defined by constants for spacing and sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e8397a53ed214fa79d1f97ed3b1e47ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
