This interactive scatterplot visualizes the Iris flower dataset, plotting sepal and petal measurements against each other. Users select which attribute appears on the X and Y axes via dropdown menus, allowing exploration of relationships between all four numeric measurements. The visualization renders as SVG circles using React components, with D3's `scaleLinear` and `extent` functions mapping data to coordinates. Axes are generated manually with `.ticks()` and custom formatting, while CSS styling controls circle and tick appearances.
