This animated scatterplot cycles through the four Iris flower measurements on the x-axis while keeping sepal length fixed on the y-axis. Colored circles (orange, blue, and white) represent the three species, with a static legend and title overlaid on a red background. The visualization uses D3 v6 APIs such as `csv`, `scaleLinear`, `axisLeft`, and `axisBottom`, and updates the x-axis every few seconds via `setInterval`. Data originates from a GitHub-hosted CSV file of the classic Iris dataset.
