This scatter plot displays the relationship between horsepower and selected attributes from the auto-mpg dataset. A dropdown menu lets users choose which column from the dataset to plot on the x-axis, while horsepower remains fixed on the y-axis. The visualization is built with d3.v5, using d3.scaleLinear for axes, d3.axisLeft and d3.axisBottom for ticks, and d3.csv to load data. The scatterPlot component renders SVG circles, with menus created by a separate dropdownMenu module.
