Ordinal Scatter Plot
This chart displays the relationship between horsepower and weight for a set of automobiles using an ordinal scatter plot, with each car represented as a red, semi-transparent circle. The visualization uses D3 version 5 to load data from a CSV file, apply linear scales to both axes, and render the plot as an SVG. The interaction between the two quantitative variables is shown by the distribution of points, with axis labels and tick marks generated via `d3.axisLeft` and `d3.axisBottom` APIs. Data preprocessing converts numeric fields to numbers before plotting.
