This interactive scatter plot lets users explore relationships between car features from a CSV dataset by selecting any column for the X and Y axes via dropdown menus. Using D3 v5, the visualization renders colored circles on an SVG canvas, with axes and labels that update dynamically. The implementation leverages `scaleLinear`, `axisBottom`, `axisLeft`, and an enter-update-merge pattern, while `transition.attr` animates the circles to their new positions over two seconds when the selected attributes change.
