This interactive scatter plot, built with React and D3, visualizes the Iris dataset, allowing users to dynamically select which sepal and petal measurements to display on the x- and y-axes through dropdown menus. The visualization employs animated transitions, using D3's `transition` API to smoothly move the circles between positions as the axes change. The plot is rendered as an SVG, with axes drawn using D3's `axisLeft` and `axisBottom` functions, and the dropdown menus are created using a custom D3 module. The data is loaded from a CSV file using D3's `csv` function.
