04 Try it yourself Interactive
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.
