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 mappings for the x- and y-axes, which include grid lines and axis labels. The visualization uses d3’s SVG rendering, with axes created via d3.axisBottom and d3.axisLeft, and data loaded asynchronously from a CSV file using d3.csv.
