{"version":"1.0","type":"rich","title":"BA 401 EXERCISE","description":"A yellow smiley face with animated eyebrows demonstrates fundamental DOM manipulation with D3.js. The face, including its red eyes and arc-shaped mouth, is drawn using SVG elements such as `circle` and `path`, with the mouth generated via the `d3.arc` function. Both eyebrows, implemented as `rect` elements, move upward and then return to their original position using chained `transition().duration()` calls over two seconds each. The code uses D3’s `select` API to manipulate the SVG directly, with all coordinates and sizes defined as constants.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71e29c2afd2246fa98d07c10273d188a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
