This scatter plot displays the relationship between horsepower and weight for cars from the auto-mpg dataset, with each point representing a vehicle. The visualization uses d3.csv to load the data and d3.scaleLinear with d3.extent to map the variables to pixel coordinates, while d3.axisLeft and d3.axisBottom generate the labeled axes with grid lines. The chart renders as an SVG with semi-transparent red circles, and the code includes a title and rotated axis labels.
