This interactive scatter plot displays the Iris flower dataset, allowing users to explore relationships between sepal and petal measurements. Two dropdown menus let viewers select which attribute appears on the x- and y-axes, updating the plot and axis labels accordingly. Data points are colored by species using a categorical scale. The visualization is built with React and D3 v5, using `d3.csv` to load data, `d3.scaleLinear` for axes, and SVG circles for marks. Axes and tick marks are drawn with custom React components.
