This interactive scatter plot explores the relationship between different attributes of cars from the UCI Auto MPG dataset. Two dropdown menus allow users to select which columns are mapped to the X and Y axes, with the points animating to their new positions. The visualization uses d3.scaleLinear, d3.extent, and d3.axisBottom and axisLeft to construct the plot, while a custom dropdownMenu function handles the selection interface. The scatter plot is rendered as SVG with a transition over two seconds.
