Work down the first column
The first entry of the column is the start point.
As you move over, if the value is zero, no action.
If the value is one, move up to the first row corresponding entry and draw an arrow to there.
A->B->C : Arrows go from A to B and from A to C
B->C->D : Arrows go from B to C and from B to D
C->D : Arrow goes from C to D
D->A : Arrow goes from D to A
