{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js smiley face demonstrates dynamic DOM manipulation with SVG and animation. The face, built from primitive shapes, shows eyebrows, eyes, nose, and mouth that shift in a looping sequence using D3 transitions. The `arc` generator constructs a curved mouth, while chained `transition().duration()` calls animate groups with 2-second movements. Positioned around the SVG center, the components rely on `attr` methods to define coordinates, and the animation cycles through offset translations before returning to the original state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e69a38dd25c4fc2ba487231bc00efc3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
