This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository. Users select which columns to map to the X and Y axes via dropdown menus. The visualization uses D3 v5's `csv`, `scaleLinear`, `axisLeft`, `axisBottom`, and `transition().duration().delay()` methods. Each data point is rendered as a semi-transparent orange SVG circle, with an animated transition as the axis mappings change.
