This interactive scatter plot visualizes the Iris flower dataset, letting users explore relationships between four measurements (sepal and petal length/width) through dropdown menus that control the x and y axes. Points are colored by species using a d3.scaleOrdinal with a corresponding legend showing the three Iris varieties. The visualization is built with React and D3 v6, rendering SVG circles and axes through custom components like AxisBottom, AxisLeft, and Marks, with data loaded via d3.csv from a remote gist.
