This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Each red, semi-transparent circle represents a car, with its position determined by the `d3.scaleLinear` scales mapping horsepower and weight values. The SVG rendering includes labeled axes with gridlines, created using `d3.axisBottom` and `d3.axisLeft`. The code loads data via `d3.csv`, converts numeric fields, and appends circles to the chart with a title, demonstrating a clear positive correlation between the two variables.
