This scatter plot visualizes the relationship between horsepower and weight for a dataset of automobiles, with each point representing a vehicle. The x-axis maps horsepower and the y-axis maps weight, using linear scales with padded margins. The visualization uses d3.csv to load the auto-mpg dataset, and employs d3.scaleLinear, d3.axisBottom, and d3.axisLeft to construct the axes with tick lines spanning the chart area. Circles are appended to an SVG group with a semi-transparent steelblue fill, and the chart includes an axis label and title.
