This animated scatter plot visualizes the Iris dataset, displaying measurements of petal and sepal dimensions. The visualization is a reusable D3 component that allows users to dynamically switch which features appear on the x and y axes through dropdown menus. Using D3's transition system, data points smoothly animate between positions when axis selections change, with circles initially appearing with a growth effect. The chart renders as SVG and uses d3.scaleLinear, d3.extent, and d3.axis functions to construct scales and axes dynamically.
