Build the college diagram, one construct at a time

The same thirteen requirement lines from section 02, drawn one symbol per press. The highlighted line is the sentence the symbol came from, so you can see which words produced which shape. Switch to Crow’s foot to redraw the finished diagram in the notation draw.io and dbdiagram.io ship with, and watch three of the Chen symbols fail to survive the move. Nothing plays on its own: Next, Back and Reset, or the arrow keys.

Chen notation · 18 steps

Amber outline = the symbol this step just drew. The diagram scrolls sideways on a narrow screen; the Fullscreen button gives it more room.
Press Next to begin. Each press draws one construct.
