This interactive scatter plot visualizes car data from the UCI Machine Learning Repository’s Auto MPG dataset. Using dropdown menus, viewers can select which numeric columns map to the X and Y axes, with the axis labels updating accordingly. The visualization is built with D3 v5, using `scaleLinear` for coordinate mapping, `axisBottom` and `axisLeft` for tick rendering, and `transition().duration(2000).delay()` for animated circle movement. The SVG scene includes gridlines with custom styling, and all data values are explicitly converted to numbers before plotting.
