This interactive scatter plot visualizes the classic Iris dataset, allowing users to explore relationships between four flower measurements by selecting which attributes appear on each axis via dropdown menus. Built with React and D3 v5, the chart uses SVG for rendering and dynamically updates scales and marks based on user selections. The visualization employs D3’s scaleLinear for positioning, CSV loading through d3.csv, and custom React components for axes and dropdown controls, while colors are randomly assigned per data point from a fixed palette.
