This scatter plot visualizes the Iris dataset, mapping petal width and sepal length as the primary axes while encoding species by color. The visualization cycles through different column pairings every two seconds using `setInterval`, animating the axes and circle positions. Built with D3 v6, it uses `scaleLinear`, `axisLeft`, and `axisBottom` for scales and axes, alongside SVG circles and custom labels. The chart is rendered on a full-window SVG, with data loaded via `d3.csv` from a remote GitHub gist.
