This scatterplot visualizes the relationship between vehicle weight and horsepower for a dataset of cars, with each point representing an individual car. The visualization uses d3.csv to load the auto-mpg dataset, then applies d3.scaleLinear to map the data to x and y coordinates. It renders the chart as an SVG using d3.axisBottom and d3.axisLeft for the axes, with gridlines and axis labels. The circles are semi-transparent steelblue points, and the chart includes a title and margin-based layout.
