{"version":"1.0","type":"rich","title":"Activity8-T4","description":"This bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes. Each car make is represented by a colored circle, with its position determined by horsepower (x-axis) and torque (y-axis), while the circle’s size corresponds to highway MPG. The color encodes the make, using `d3.interpolateTurbo` and `scaleOrdinal`. The visualization, built with D3 v7, uses the `join` API to create SVG circles, and includes interactive tooltips that appear on mouseover. A legend with circles and lines shows the MPG scale, and another legend maps color to car make.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1b0875d07e3414c8140326bce5e77af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
