This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, with each car represented as a red, semi-transparent circle. The chart uses D3.js v5, specifically the `scaleLinear` function for scaling, `axisLeft` and `axisBottom` for the axes, and `extent` to compute the domain from the data. The data is loaded from a CSV file via `csv`, and the visualization is rendered as an SVG. The styles include custom fonts and tick formatting, with axis labels and a title displayed prominently.
