This animated scatterplot cycles through the four Iris flower measurements on the x-axis, using D3 v6 to load data via CSV and render SVG circles colored by species. The chart employs a reusable `scatterPlot` module with `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to build axes, while a `setInterval` timer updates the x-value mapping every few seconds. Custom legend labels and axis titles are dynamically appended to the visualization.
