This scatter plot displays the relationship between horsepower and torque for a set of vehicles, with each data point rendered as a distinct symbol representing a categorical attribute. The visualization uses D3 v7 scales and axes to map the quantitative variables, while an ordinal scale assigns different symbol shapes from `d3.symbolsFill` to encode the categorical dimension. A custom legend explains the shape-to-category mapping, and the data is loaded from an external CSV file using `d3.csvParse`.
