Scatter Plot with Menus
This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, showing relationships between car attributes. Users select which columns map to the X and Y axes via dropdown menus built with a reusable `dropdownMenu` function. The visualization uses D3 v5 scales (`scaleLinear`), axes (`axisBottom`, `axisLeft`), and SVG transitions that animate circles into position over two seconds. Axis labels update dynamically, and the dataset includes numeric columns like mpg, cylinders, displacement, horsepower, weight, acceleration, and year.
