Graph of transpositions from Sicilian Defence #chess

One of the most common first moves for white in the game of chess is e4, i.e. white king's pawn moves ahead two squares. I know people who open their games only in this way. One of black's strongest responses is to move a pawn to c5, and thus start the Sicilian Defense, which makes it a good opening to study.

The following graph illustrates possible transpositions from Sicilian Defense. White boxes signify moves of the white player and gray boxes show moves for the black. The transition from box to box is labeled with a name of a respective opening line, from most general early in the decision tree to most specific down in the leaves.
