Organization charts in PowerPoint are geared toward showing people and their relative positions in a company. The default org chart is inserted with just a few shapes—one at the top for the boss and three below it for workers at the next level. You build on this, using these types:
These shapes show below the person being reported to and above that person's subordinates.
These are inserted directly below the person they report to, and they branch horizontally or vertically (your choice) for multiple shapes.
These line up next to shapes on the same reporting level. They can also be added as subordinates to the same boss.
