{"version":"1.0","type":"rich","title":"act3_task4","description":"This example combines a D3.js v7 bubble chart with an animated smiley face to demonstrate DOM manipulation. The bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, using `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for color, and interactive tooltips on circle hover. The smiley face uses `d3.select` and `transition` to animate its eyebrows up and down. The chart loads data from a CSV file, while the face is built entirely with SVG shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b96364d3d2c4776a23a51e4562dbcfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
