This interactive scatter plot displays the Iris dataset, letting users compare any two numeric flower measurements via dropdown menus. The visualization colors each point by iris species and includes a legend. Built with D3 v5, it uses scaleLinear for axes, scaleOrdinal with schemeCategory10 for coloring, and d3.csv to load the data. The circles animate into place using a 2-second transition with staggered delays, rendered as SVG elements.
