This is interesting, but you would be naive if you think this is in any way comprehensive or accurate.
My religion and main area of knowledge of Catholicism shows a limited number of picked and chosen orders of priests, (i.e. Franciscans, Cistercians, Capuchins). These are not separate religions by any means whatsoever; they are all members of the Catholic faith. They certainly don't belong on a chart that is meant to display different religions and schisms.
According to the key, they are listed as "adherent branches".
Schisms are shown by ovoids with white fill and appear to make some sense.
I guess the chart is trying to show practices that have a lot of adherents, not just a diagram of religions. Much of the problem is probably just using the word "branch", which isn't a great description of what is shown.
That's true I believe. However, my point is that at least in the Christianity (specifically Catholicism) sector of this graph, it's misleading.
Specifically in the graph, different orders of priests aren't schismatic offshoots of the Catholic religion by any means.
After looking at the graph a little more closely, I also see various Catholic traditions listed as separate religions (i.e. Syro-Malabar Catholic Church, Ruthenian Catholic Church, Melkite Greek Catholic Church). I understand the idea of listing these as separate from the Church, but they are in "full communion" with the Catholic Church and also shouldn't be mistaken as separate religions. We all believe the same important things, different cultures and traditions have brought their own gifts to the faith.
Catholics profess the Nicene Creed each mass and in it are the "Four Marks of the Church", something every Catholic grade schooler has to memorize at some point. One, holy, catholic, and apostolic. The word "Catholic" itself is greek for "universal".
Someone shared a chart with me the other day that, while not quite the same thing, could be of interest to those wondering what happened to the core followers of Jesus who went on to found the early local churches:
