Unfortunately, the text is tiny, (and not in English.) The circle on the left side with the three parts looks like a stylized map of the world also attributed to Beatus, and the squiggly text looks like it says "Europa" and "Asia". (North is to the left.) I think Africa is labeled "Lybia".
The rest of the chart is a mystery to me.
This is the right side of the page, where the flowchart ends with the Adoration of the Magi.
