Cars Scatter Plot with Menu
This scatter plot displays automobile data from the UCI Auto MPG dataset, allowing users to explore relationships between variables like horsepower, weight, and acceleration. Two dropdown menus let viewers select which attributes appear on the x- and y-axes, while a color legend filters points by country of origin (USA, Japan, Germany). Built with d3.v5, the visualization uses `scaleLinear` and `scaleOrdinal` for scales, `axisBottom` and `axisLeft` for axes, and custom `colorLegend` and `dropdownMenu` modules for interactive controls. Points render as SVG circles with tooltips showing car names.
