This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, with each circle representing a vehicle. The visualization is built using D3 v5 with SVG rendering, employing `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct the axes and scales. Data is loaded asynchronously from a CSV file via `d3.csv`, with numeric fields parsed for accurate plotting. The chart includes labeled axes, a title, and semi-transparent red circles, with gridlines generated through tick size adjustments.
