{"version":"1.0","type":"rich","title":"Activity 7 Task 5","description":"This visualization displays a bubble chart correlating average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its radius represents highway MPG and color distinguishes car brands. The chart includes interactive tooltips on hover, a legend for MPG sizing, and a color-coded brand legend. Rendered as SVG with D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.interpolateTurbo`, and `d3.csv` to load data from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0ecc881e06e84258a9d3264fba68b54f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
