This scatter plot displays the relationship between horsepower and weight for a collection of cars, with each circle representing a vehicle. The visualization uses D3.js (v5) to render the plot as an SVG, scaling the data from the included auto-mpg.csv file, which originates from the UCI Machine Learning Repository. The code employs `scaleLinear`, `extent`, and the `axisLeft` and `axisBottom` functions to construct and label the axes, while the circles are appended to the SVG group using D3's selection and data-binding methods.
