This bubble chart shows the correlation between average horsepower, torque, and highway MPG across various car makes. Each circle represents a make, positioned by horsepower on the x-axis and torque on the y-axis, with bubble size scaled to highway MPG using a linear scale and color assigned via an ordinal scale with interpolated turbo colors. The visualization includes a tooltip displaying the make on hover, a legend showing MPG values, and is rendered as an SVG with d3.v7, using scales like `d3.scaleLinear` and `d3.scaleOrdinal` alongside axis generators. Data comes from the included CSV file.
