If you have already created a graph, then you can create a block layout next. If you want to execute a single layout algorithm, select the Select Layout command. If you selected the Tiled space allocation method, generating even a single layout for large projects might take a long time to complete. If you want to execute all block layout algorithms in sequence and retain the block layout with the minimum shape adjusted distance score, select the All Layouts command. Because of its extensive computations this last command might take a long time to complete.
Finally, if you want to execute all graph algorithms and for each graph algorithm execute all layout algorithms, select the All Graphs and Layouts command. Because of its extensive computations this command may take a long time to complete.
