This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across three iris species. The visualization uses dropdown menus to dynamically switch which attribute is mapped to the x-axis and y-axis, with axes and labels updating accordingly. Built with D3 v5 and React, the example uses `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render SVG circles colored by species, with gridlines and axis labels providing clear context for the selected variables.
