A scatterplot of the Iris dataset allows users to explore relationships between flower measurements by selecting which attributes appear on the X and Y axes via dropdown menus. The visualization uses React for component-based UI, with D3 v5’s `scaleLinear`, `extent`, and `csv` for data loading and scaling, rendering SVG axes and circle marks. Each point includes a tooltip showing the formatted X-axis value. The Iris data is fetched from a remote CSV file, and axis labels update dynamically based on the selected attributes.
