The x-axis represents horsepower, the y-axis represents torque, and the size of each circular marker indicates the vehicle's highway fuel efficiency. Data is loaded from a remote CSV file and rendered as SVG circles, colored by car brand using `d3.scaleOrdinal`. Hovering over a bubble triggers an animated tooltip displaying the exact values, while the radius and opacity scale through `d3.scaleLinear`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/356d0715993b4ac2b9cffb0af30aba6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
