This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. The code uses d3.csv to load the data, d3.scaleLinear for both axes, and d3.axisLeft and d3.axisBottom to render tick marks and labels. Each car is drawn as a red, semi-transparent SVG circle positioned by its scaled horsepower and weight values. The chart includes axis labels and a title, rendered via SVG text elements with custom CSS styling for font sizes and colors.
