This scatter plot explores the relationship between different attributes of cars from the UCI Machine Learning Repository’s Auto MPG dataset. Users select which columns to map to the X and Y axes via dropdown menus, built with custom D3 code that creates and updates `<select>` elements. The visualization itself uses `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom` to render axes and SVG circles, with a staggered `transition().delay()` animation that moves points from the center to their final positions over two seconds.
