{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A D3.js bubble chart displays the correlation between average horsepower and average torque for different car makes, with bubble size and color encoding highway MPG. The visualization uses `d3.scaleLinear` for positional and size mappings, and `d3.scaleOrdinal` with `d3.interpolateTurbo` for categorical coloring. Hover interactions trigger tooltip handlers that show the car make. The chart is rendered as SVG and includes a legend for both bubble size and color categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93cae9c5e7e04730a140885b73019299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
