This interactive scatterplot animation cycles through the four Iris flower measurements (petal width, sepal width, petal length, sepal length) from the classic Iris dataset, updating the x-axis every few seconds while keeping sepal length on the y-axis. Data points are color-coded by species, with a legend, axis labels, and title rendered via SVG. The visualization uses the D3.js library (v6.7.0) with a custom `scatterPlot` module that leverages `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` for chart construction, while `setInterval` drives the animation.
