1. A method for displaying performance of a wellbore drilling operation including wellbore cleaning, comprising: defining drilling parameters for the drilling operation; defining a visualization tool comprising a boundary defined by the drilling parameters, wherein the boundary depicts an optimal rate of penetration (ROP); displaying the visualization tool with the optimal ROP, wherein the optimal ROP defines a maximum ROP for optimal wellbore cleaning based on the drilling parameters; displaying an actual rate of penetration (ROP) with respect to the optimal ROP on the visualization tool; and adjusting the actual ROP to match the optimal ROP.
