This interactive scatter plot visualizes car data from the UCI Machine Learning Repository's Auto MPG dataset, allowing users to explore relationships between numerical attributes. Two dropdown menus let the viewer select which columns from the dataset map to the X and Y axes, with selections triggering a re-render. The visualization is built with D3 v5, using `scaleLinear` for axes, `axisLeft` and `axisBottom` for tick marks, and animated circle transitions via `transition().duration()`. The plot updates smoothly, displaying data points as semi-transparent red circles over a clean SVG canvas.
