{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing an animated smiley face from basic SVG shapes. A yellow circle forms the head, with separate groups for eyes, eyebrows, and a rectangular nose. Using `d3.select` and `append`, the code builds each element, then animates the eyebrows and nose vertically with `transition().duration(2000)`. The mouth is drawn using the `arc()` generator from the `d3-shape` module. The result is a playful illustration of D3’s data-join-free approach to direct SVG element creation and chained transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b995523f7e24fcda20206106a427594?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
