This scatter plot shows the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set, with each car represented by a semi-transparent red circle. The visualization uses d3.scaleLinear to map the data to x- and y-axes, with gridlines drawn via d3.axisBottom and d3.axisLeft. The svg rendering includes axis labels and a title, while the data is loaded from a CSV file using d3.csv.
