We describe Dalitz plots arising in studies of D-meson decays, and what we
have learned from them in recent years. After some mention of technique and
history, we focus on decay of the D± and Ds±​ mesons to the
K−K+π± final state, and on Ds±​ decay to π+π−π±.
Some mention of other Dalitz plots involving D-meson decays is also made.Comment: To appear in the proceedings of The 5th International Workshop on
