This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements by switching the x-axis attribute via a dropdown menu. Built with React and D3 v5, the visualization renders SVG circles for each data point, with axis components (AxisBottom and AxisLeft) generating tick marks and labels. The code uses d3.scaleLinear, d3.extent, and d3.csv for data loading and scaling, while ReactDropdown provides the interactive menu. A native SVG `<title>` element serves as a basic tooltip, displaying the x-axis value for each point on hover.
