This interactive scatterplot displays the relationship between horsepower and weight for cars, with circles colored in a semi-transparent blue. Users can toggle checkboxes to switch the x-axis mapping from horsepower to a separate origin scale. The visualization uses D3.js v5 for data binding, scales, and axes, with data loaded from a CSV file via `d3.csv()`. The SVG rendering includes gridlines and axis labels, and jQuery handles the checkbox interactions that reassign the circle positions.
