This interactive scatter plot visualizes the Iris dataset, allowing users to select any two of the four features (sepal length/width, petal length/width) for the X and Y axes via clickable buttons. Data points are colored by species (setosa, versicolor, virginica) and rendered as SVG circles. Built with D3 v5, the visualization uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for tick marks, and a custom `buttonPanel` module to handle interactive selections.
