This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset, using red semi-transparent circles. The D3.js v5 code loads CSV data, parses numeric fields, and renders an SVG with linear scales, axes, grid lines, and labels. It uses `d3.csv`, `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to position circles and generate the visualization.
