This scatterplot shows the relationship between horsepower and weight for a dataset of cars, with each point representing a vehicle. The visualization uses a linear scale to map both variables along the x and y axes, with gridlines and labeled axes for clarity. The code loads data from a local CSV file using d3.csv, transforms the numeric columns, and renders the chart as SVG circles using D3 v5's scaleLinear, axisBottom, and axisLeft APIs. The points are semi-transparent blue circles, and the chart includes a title and rotated axis labels.
