A scatterplot of the Iris dataset displays measurements of sepal and petal dimensions. A dropdown menu above the chart lets the user select which two attributes to plot on the X and Y axes, updating the scatterplot and axis labels accordingly. Built with React and D3 v5, the visualization uses `d3.scaleLinear`, `d3.extent`, and `d3.csv` to load and scale the data, with SVG circles rendered via React components.
