This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, with each red circle representing a vehicle. The visualization uses d3.csv to load the data, d3.scaleLinear for both axes, and d3.axisBottom and d3.axisLeft to render the tick marks and labels. The SVG rendering includes axis labels, a title, and grid lines created by extending ticks across the plot area, with data points displayed at 10-pixel radius and 30% opacity.
