This interactive scatter plot displays the Iris flower dataset, allowing users to select which quantitative attributes to plot on the x- and y-axes via two dropdown menus built with React and the ReactDropdown component. The visualization is rendered as an SVG using D3 v7 scales (scaleLinear) and custom axis components, with circles colored in a teal tone and tooltips showing the formatted attribute values. The code loads CSV data via d3.csv and uses React hooks (useState, useEffect) to manage state and fetch the data.
