This interactive scatter plot visualizes the Iris Dataset, displaying sepal and petal measurements as a series of circles. Two dropdown menus allow the user to independently select which quantitative or categorical attribute is plotted on the x- and y-axes. The visualization is built with React and D3 v5, using `d3.scaleLinear` and `d3.extent` to map data to SVG coordinates, while axis components and marks are rendered as reusable React functions. Data loading is handled asynchronously with `d3.csv`, and the chart updates dynamically when menu selections change.
