This scatter plot visualizes the relationship between miles per gallon (MPG) and horsepower for a dataset of cars, with each circle representing a vehicle. The chart uses color to differentiate individual data points, while axes are labeled and scaled using D3's `scaleLinear` and `scaleBand` functions. Built with D3 v5, the visualization renders as an SVG and reads its data from an external CSV file. The code employs D3's `axisLeft`, `axisBottom`, `extent`, and `format` APIs to construct the axes and tick marks.
