This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across three flower species. Dropdown menus let viewers select which measurements appear on the x- and y-axes, updating the plot dynamically. The SVG rendering uses d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.scaleOrdinal, with species colored in orange, teal, and purple. The dropDownMenu component, built with d3-selection, binds options to each select element. Axis labels, gridlines, and a color legend convey measurement units and categorical distinctions.
