can represent dependency between processes with a 2d chart where each axis is the time progress on each task

if there is no dependence, all paths from start (bottom left) to end (top right) are available

dependence represented as a “bottom-right” space of the chart

route of actual work and proximity to “area of demand” indicates how efficient the actual work is

can represent mutual dependencies with a dependence area on the “top-left” space
