This interactive scatter plot displays automotive data from the UCI Machine Learning Repository Auto MPG dataset, allowing users to dynamically select which columns map to the X and Y axes via dropdown menus. Built with D3 v5, the visualization uses `d3.csv` to load data, `d3.scaleLinear` for scaling, and `d3.axisLeft` and `d3.axisBottom` for axes. Each selection triggers a re-render where circles transition smoothly over two seconds into their new positions using `transition.attr`. The SVG-rendered plot features red, semi-transparent points and labeled axes that update to reflect the chosen variables.
