This interactive scatter plot visualizes the Iris dataset, plotting measurements like petal length and sepal width against each other. It uses color to distinguish the three Iris species, with a dropdown menu letting users select which attributes appear on the X and Y axes. Built with React, D3, and rendered as SVG, the code defines custom `AxisBottom`, `AxisLeft`, and `Marks` components that leverage D3's `scaleLinear` and `scaleOrdinal` for scaling, along with tooltips showing values on hover.
