This interactive scatter plot visualizes the Iris Dataset, displaying measurements from four flower attributes. Users select which attributes appear on the X and Y axes through two dropdown menus, with axis labels and scales updating accordingly. The visualization is built with React and D3 v7, using `scaleLinear`, `extent`, `max`, and `format` functions to position marks and format tick labels. SVG circles represent individual iris samples, with native `<title>` tooltips revealing exact values on hover. The example demonstrates a polished, reusable component architecture with axes, marks, and dropdowns split into separate functional components.
