This interactive visualization displays Fisher's Iris flower dataset as a scatter plot, allowing users to select which flower measurements (sepal length, sepal width, petal length, or petal width) appear on the x and y axes via dropdown menus. Each flower is rendered as an SVG circle, with D3 scaling below the threshold. Built with React and D3 v5, the code utilizes D3’s `scaleLinear`, `extent`, and `csv` functions for data loading and scaling, while custom `AxisBottom`, `AxisLeft`, and `Marks` components handle chart rendering.
