From the opening

The shape of a district is the boundary that decides which homes vote together for a seat. Change the shape and you change the electorate inside the contest, so the same voters and the same preferences can produce a different winner because they were grouped differently. The opening covers boundaries choose the electorate, packing piles up safe seats, and cracking splits a group thin.
