This scatter plot maps horsepower on the x-axis against weight on the y-axis for a dataset of cars from the auto-mpg CSV. Each semi-transparent teal circle represents a vehicle, with axes, gridlines, and descriptive labels rendered using D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft`. The SVG chart is built by appending circles and axis groups within a margin-based layout, with data parsed and converted to numeric values before rendering.
