Flip the graph around and the Romans make a contiguous line instead. Talk to a protestant and they'll add an extra line and say they have the oldest and longest tradition. I appreciate the effort, but this isn't the most helpful way to understand church history.
One of them is that orthodoxy is missing one big schism, which was the schism between the ROC and the old believers, who completely split from communion with the eastern orthodox church and constitute their own branch of Christianity. They are to orthodoxy what protestantism is to catholicism, albeit much smaller in number.
It's also missing the oriental orthodox (not to be confused with eastern orthodox) schism from the chalcedonian church long before the east-west schism.
