A scatter plot with dropdown menus for exploring the iris dataset, allowing interactive selection of the attributes plotted on the x and y axes. The visualization uses React with D3 v5’s `scaleLinear` and `extent` functions for scaling and axis generation, rendering SVG circles as marks. The dropdowns update the selected attributes via state management, triggering re-renders of the axes and data points. Data is loaded from a remote CSV file using D3’s `csv` function.
