This interactive scatter plot explores the Iris Dataset, displaying three flower species distinguished by color. Users select which measurements appear on the x- and y-axes via dropdown menus built with d3.select and event listeners. The visualization uses d3.scaleLinear for axes, d3.axisBottom and d3.axisLeft for ticks, and SVG circles with dynamic positioning. Data loads from a remote CSV file using d3.csv, demonstrating a classic D3 v7 workflow.
