This interactive scatter plot from the Iris Dataset lets users explore relationships between different measurements by selecting which features to plot on the X and Y axes via dropdown menus. Built with React and D3 v5, it renders circles as SVG marks with tooltips showing formatted values, using d3.scaleLinear for axes and d3.extent for domain calculation. The ReactDropdown component from react-dropdown manages the attribute selection, while custom AxisBottom, AxisLeft, and Marks components handle the grid and data points.
