This scatter plot visualizes the relationship between horsepower and weight for individual cars from the auto-mpg dataset. Each red, semi-transparent circle represents a vehicle, positioned according to its horsepower and weight values. The visualization uses D3.js version 5.6, specifically leveraging `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes and plot the data as an SVG. The code parses the remote CSV file, converting numeric fields, then renders the scatter plot with custom margins and axis labels.
