This interactive scatterplot animates through the Iris flower dataset, cycling the x-axis among four measurements (petal width, sepal width, petal length, sepal length) while the y-axis shows sepal length. Points are colored by species (setosa in blue, versicolor in green, virginica in orange) with a custom legend. The visualization uses D3 v6 APIs including `csv`, `scaleLinear`, `axisLeft`, `axisBottom`, and `selectAll().join()`, with the plot constructed as a reusable `scatterPlot` function. A `setInterval` timer redraws the axes and updates the x-value mapping, while static labels and a title appear as SVG text elements. Data loads from a remote gist CSV file.
