This interactive scatter plot lets users explore the auto-mpg dataset by selecting which columns to plot on the x- and y-axes via dropdown menus. The chart renders as an SVG with axes and gridlines, and circles animate into position using D3 transitions with staggered delays. The implementation uses d3.scaleLinear, d3.extent, d3.axisBottom, and d3.axisLeft, with a custom dropDownMenu component managing the select elements.
