This interactive scatter plot displays the classic Iris dataset, showing measurements of sepal length, sepal width, petal length, and petal width. Users can select which attributes to plot on the x and y axes from dropdown menus, and the visualization updates dynamically. The points are colored by species class using a D3 ordinal scale. The code uses D3.js v7 to load the CSV data, create linear scales for both axes, and render the plot as an SVG, updating the circles and axes on each selection change.
