The transform is the last column of this table. It is a permutation of the input — the same characters in a different order — so its zeroth-order entropy is exactly the input's, 3.899 bits per symbol, and by that measure nothing has happened. What has happened is that characters sharing a following context now sit together: on a 8,192-symbol stream the mean run goes from 1.01 to 3.38, and a move-to-front pass turns that into a floor of 1.80 bits per symbol against 4.16.

4 essays call bwt-columns. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about — which is what optcheck and figfill exist to catch.
