This D3 scatter plot visualizes the relationship between horsepower and weight for a set of cars, with each point representing a vehicle. The data is loaded from a remote CSV file and parsed into numeric values. The code uses `scaleLinear` to map the data range to the SVG canvas, `axisLeft` and `axisBottom` for the axes, and `format` for tick labels. Circles are appended with a fixed radius, and the plot includes a title and axis labels. The SVG rendering is styled via CSS for a clean presentation.
