This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars from the UCI Machine Learning Repository's Auto MPG Data Set. Each red semi-transparent circle represents a car, with its x-position mapped to horsepower and y-position to weight. The visualization is rendered as an SVG using D3 v5, employing `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while CSS styles the circles and text elements. The data is loaded via D3's `csv` function from a remote URL.
