{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with moving eyebrows demonstrates D3.js v5 DOM manipulation. The code builds the face using SVG shapes, appending a circle for the head, two circles for eyes, rectangular eyebrows, and a path generated with the `arc()` function for the mouth. The eyebrows animate upward and downward over two seconds using chained `transition()` and `attr()` methods. This example highlights fundamental D3 selection, attribute setting, and transition functionality.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c71e2ea620874d3b8aa03ba555891a2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
