This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, with each circle representing a vehicle. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear`, `axisLeft`, and `axisBottom` to construct the axes and gridlines. Data is loaded via `csv()` from an external file, and circles are appended to the chart with opacity set to 0.5. The chart includes labeled axes and a title, with margins creating space for the axis annotations.
