This visualization compares car statistics by plotting miles per gallon (mpg) against horsepower for 32 car models. Each car is represented as a circle on a scatterplot, with axis labels and gridlines provided by D3’s `axisBottom` and `axisLeft` functions. The data comes from a CSV file, parsed with `d3.csv`, and rendered as an SVG using `d3.scaleLinear` for both axes. The cars are sorted by horsepower, and the circles are styled with steelblue fill and opacity.
