This interactive bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across car makes. Each circle represents a car brand, with x-position indicating horsepower, y-position torque, and circle size scaled to MPG values. The visualization uses D3 v7 to load CSV data, render SVG elements, and implement brushing and zooming. Interactive tooltips display the car make on hover, while legend circles indicate MPG size scaling and colored dots distinguish each brand.
