This interactive scatter plot visualizes the Iris dataset, comparing two user-selected measurements of iris flowers. The chart encodes flower species with a color scale using d3.scaleOrdinal and displays the data as circles rendered in SVG by React components. Dropdown menus built with the React-Dropdown library allow switching between sepal and petal measurements for the x and y axes, using d3.scaleLinear for scales and d3.extent for domains. The axes are drawn with custom SVG components using d3.ticks for tick marks.
