This interactive scatter plot explores car data from the UCI Machine Learning Repository’s Auto MPG dataset. Users select which columns to plot on the X and Y axes via dropdown menus that update the chart dynamically. The visualization uses D3 v5 with SVG rendering, including `d3.csv` for data loading, `d3.scaleLinear` and `d3.extent` for scales, and `d3.axisBottom`/`d3.axisLeft` for axes. Each point’s position animates over two seconds via `transition().duration(2000)`, with a delay per circle, creating a smooth reapportionment when variables change.
