An interactive scatter plot visualizes the Iris dataset, displaying measurements of sepal length, sepal width, petal length, and petal width across three iris species. Users select which measurement appears on each axis through Bootstrap dropdown menus. The visualization uses d3.csv to load data, d3.scaleLinear for axes, d3.scaleOrdinal with schemeCategory10 to color points by species, and d3.axisBottom and d3.axisLeft for tick marks, all rendered as SVG elements with a transparent circle effect.
