This interactive scatter plot displays the classic Iris dataset, allowing users to explore relationships between sepal and petal measurements. Two dropdown menus let viewers independently select which attribute appears on the x- and y-axes, with axes and labels updating dynamically. Built with React and D3 v7, the visualization uses `scaleLinear` for coordinate mapping and renders data points as SVG circles. The data is loaded via D3's `csv` parser, and reusable axis and mark components keep the code modular.
