{"version":"1.0","type":"rich","title":"Question1","description":"A bubble chart displays the correlation between average horsepower, torque, and highway MPG across car makes. Using D3 v7, it reads data from a CSV file and renders SVG circles positioned by the x and y axes, with circle size encoding highway MPG and color mapping to car make via `d3.scaleOrdinal` and `d3.interpolateTurbo`. Interactive tooltips appear on mouseover. Legends show MPG ranges and make colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b3881f393a64f519ba10630198afe76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
