{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This visualization compares average horsepower, torque, and highway MPG across car makes using a bubble chart. Each bubble’s position encodes horsepower and torque on the x- and y-axes, while its radius represents highway MPG and its color distinguishes the car brand. Built with D3 v7, the chart uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for categorical colors, and SVG circles with mouseover tooltips. A legend displays MPG values and makes, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff588a0dc1964e2db01e392644220799?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
