Inspiration for this post This post comes from the finishing touches I needed to put on a paper about life history evolution. The paper compares life history traits across the four groups of tetrapods (amphibians, reptiles, mammals, and birds), so when I carried out the nitty gritty phylogenetic analyses, I used four separate phylogenies. When it came time to make a figure to visualize those analyses, however, I ended up with an unwieldy (and unpublishable) 16-panel figure (four phylogenies by four traits).
