{"version":"1.0","type":"rich","title":"Activity_6Task4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes its make’s horsepower (x-axis) and torque (y-axis), while the radius scales with highway MPG and color categorizes the brand. Built with D3 v7’s `scaleLinear` and `scaleOrdinal` APIs, it renders as an SVG with an interactive tooltip that appears on mouseover. The data is loaded from a local CSV file, and a legend explains the MPG bubble sizes and color-coded makes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b055d17a2cf462589ad9098063371bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
