{"version":"1.0","type":"rich","title":"Activity_6_Task_4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each bubble's position mapped to horsepower and torque axes while its radius encodes fuel efficiency. The color of each bubble distinguishes the car manufacturer. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.interpolateTurbo` for color mapping, and includes interactive tooltips that display the car make on mouseover. Data is loaded from a CSV file and rendered as SVG with animated hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a64d83fad3d46f9ae0777d059a811bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
