How did the project planners visualize task dependencies in the p

The project planners visualized task dependencies in the project plan using a PERT Chart. This chart allowed them to see that two tasks were dependent without resources. The dependencies were represented by blue arrows in the visualization.

Question was asked on:

One of the ways the project saved time was by not waiting for the town to be built before they started work on the dam. *If this was visualized on a PERT Chart, the project planners could see that the two tasks were dependent without resources, as noted by the blue arrows in the above visualization. Since one required concrete and steel and the other required lumber and food. Because they started in 1931, two years into the Great Depression, they had access to a wealth of workers looking for a job. So workers started six months ahead of schedule and lived in a "rag town" while they waited for utilities to be piped in from 500 miles away.
