This interactive scatterplot displays the Iris dataset, allowing users to explore relationships between sepal and petal measurements. Dropdown menus let users switch any axis between quantitative measurements or the categorical species attribute, with points smoothly animating to new positions over two seconds. Species are distinguished by both color and different geometric symbols, and axes and titles transition accordingly. Built with D3 7.9, it uses `scalePoint` for categorical axes, `scaleLinear` for quantitative ones, `transition` for synchronized animations, and `symbol` for marker shapes, rendering as SVG.
