Influenza lineage phylogram

This illustrative phylogram groups a small set of influenza A labels into H1N1, H3N2, and H5N1 clades. Bootstrap values are carried as annotations in the Newick string and colored highlights make each group readable at a glance. The figure demonstrates how to present a result, but it is not a substitute for an alignment, model selection, or phylogenetic inference from real sequences. Before using the layout in a build or document, compare every label with the source requirements and update the drawing when parts, conditions, or materials change. The example is deliberately small so the essential relationships remain readable, easy to review with collaborators, and ready to extend with the details required for the actual project.
