	4	+The Sugiyama algorithm consists of 5 phases: cycle breaking, layer assignment, crossing minimization, node placement and edge routing. Node placement sets the x-coordinates of nodes (in a downward layout) and creates alignment between nodes, improves edge straightness, or balances nodes based on their incoming edges. Node sizes can also be used to eliminate edge bends by increasing the size of nodes, as seen below, which makes the drawing easier to read, edges easier to follow and therefore easier to understand.
