This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between four flower measurements via dropdown menus that select the variables for the x and y axes. Built with React and D3 v6, the visualization uses SVG circles and linear scales to plot data points, with axis labeling and tick formatting provided by custom components. The code leverages D3's `scaleLinear` and `extent` for scaling and domain calculation, and CSV data loading through the `csv` function, all rendered within a React-based SVG framework.
