{"version":"1.0","type":"rich","title":"T8 Question 9","description":"This visualization shows the correlation between average horsepower, torque, and highway MPG for a set of fictional vehicle makes. Each circle’s position encodes horsepower and torque on the x and y axes, while its radius represents highway MPG and its color distinguishes the make. The chart uses D3 v7 with SVG rendering and animation, employing `d3.csv` to load data, `d3.scaleLinear` and `d3.scaleOrdinal` for scaling, and interactive tooltips on hover. A legend displays both MPG circle sizes and color-coded makes. The data comes from a CSV file loaded dynamically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59ea21d85ab546f2be02affefb059954?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
