{"version":"1.0","type":"rich","title":"smile sad","description":"This example renders a yellow, black-outlined smiley face using D3.js version 7, loaded via UNPKG. The face is composed of circles for the eyes and a path built with the `arc` function for the mouth. An animated sequence uses chained `transition()` calls with a 2-second duration to move the eyebrows down and then back up, creating a toggle between a sad and happy expression. The SVG output is centered within a 960 by 500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b67e4c441914b8ea0b6c249456909d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
