This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements. Two dropdown menus let viewers select which attribute to plot on the x-axis and y-axis, with the chart dynamically updating the scales and axis labels. Built with React and D3 v7, the visualization uses `scaleLinear` for axes, `extent` for domain calculation, and SVG rendering for the scatterplot marks. Data is fetched from a GitHub gist using D3's `csv` loader, with axis components defined as reusable React functions.
