This scatter plot visualizes the relationship between horsepower and weight for a collection of cars, with each point representing a single vehicle. The chart uses red, semi-transparent circles to reveal overlapping data density, and displays axis labels and a title against a clean white background. The visualization is built with D3 v7, leveraging `select`, `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load the auto-mpg dataset, scale the axes, and render the SVG output. Axes are customized with tick lines, and the data points are positioned using the linear scales.
