This animated scatter plot displays the Iris dataset, cycling through four different feature pairings on the x-axis while keeping sepal length on the y-axis. Individuals are colored by species (setosa, versicolor, virginica) with a legend. The visualization leverages D3 6.7.0 via UNPKG, using modules like `scaleLinear`, `extent`, and `axisBottom` from a custom `scatterPlot` module to render SVG circles, axes, and text labels. Data loads from a remote CSV, and animation runs on a timer that re-renders the plot with new column assignments.
