This interactive demo showcases a reusable scatter plot built with D3.js, visualizing the classic Iris dataset. It cycles through four flower measurements every two seconds, swapping the x-axis variable while maintaining the y-axis, so the changing distributions and correlations between sepal and petal dimensions are easy to compare. The plot uses D3's `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` functions within a custom `scatterPlot` module, drawing SVG circles and updating them in place with a `setInterval` timer. The data is loaded remotely from a CSV file via `d3.csv`.
