Coding with the Draw Commands on TI-Nspire CX II

Check out the new CANVAS / Drawing features on the TI-Nspire CX II and TI-Nspire CX II CAS. There is so much mathematics you can do with something as simple as drawing lines. How large is the drawing canvas? What is the syntax for the draw commands? What mathematics can I do with coding? The TI-Nspire CX II drawing commands can add fun and interest to mathematics including interesting ways to visualise multiplication; cardioids and much more.
