{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A yellow face with eyes and eyebrows is drawn in SVG using D3.js. The eyebrows animate up and down through chained `transition` and `duration` calls, while the mouth alternates between a frown and a smile using `setTimeout` to invoke a custom `mouthFunction` that redraws an arc path via D3's `arc` generator. The code uses `select`, `append`, and `attr` to build the face from primitive shapes, and `exit` and `remove` to replace the mouth path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ca89884f8364db1b080bacc1d3c7065?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
