A polished interactive scatter plot of the Iris dataset lets users explore relationships between sepal and petal measurements. Two dropdown menus, built with react-dropdown, control which attribute appears on the X and Y axes, dynamically updating the axis labels, scales, and point positions. The visualization uses React with hooks for state management and D3.js (d3.scaleLinear, d3.extent) to map data to SVG circle marks, with tooltips showing values. Data loads via d3.csv from a GitHub gist, and custom React components render the axes and dropdowns.
