Interactive scatter plot of the Iris dataset using React, D3 v5, and SVG, which visualizes relationships between sepal and petal measurements. Users can switch the X and Y axes via dropdown menus to explore different attribute combinations. A categorical color scale (`d3.scaleOrdinal`) distinguishes the three iris species, with `d3.scaleLinear` mapping numeric coordinates. The plot includes formatted axes and tooltips showing values on hover.
