This interactive scatter plot of the Iris dataset cycles through four different x-axis measurements—petal width, sepal width, petal length, and sepal length—at regular intervals, while the y-axis remains fixed on sepal length. Points are colored by species (orange, blue, and white circles). Built with D3 v6, the visualization uses `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` within a reusable `scatterPlot` module, updating axes and rendering via SVG on a black background with a custom legend and title.
