This scatter plot visualizes the Iris dataset, letting users interactively explore relationships between sepal and petal measurements by selecting which attribute appears on each axis via dropdown menus. The visualization uses D3.js v5 scales (scaleLinear, scaleOrdinal) to map data values to positions and colors, while the React-driven SVG rendering displays circles for each flower specimen. Species are distinguished by color, and hovering reveals the x-axis value through a native SVG tooltip. The code implements custom React components for axes and marks, with data loaded asynchronously from a CSV file.
