Why isn't my node setup working to create a smoke effect in cycles? I looked up how to do smoke in cycles, and ended up here. Following their setup, I ended up with a completely transparent object. I tried to apply the material to a cube, and placed a Suzanne head (with no material applied) behind it to better see the effect. I have attached images of the scene in solid view and rendered view, as well as an image of my material nodes. If other screenshots or info are needed, just ask.
Alright, I'm a fool. Thanks to pycoder for pointing out my error. I forgot to add the Quick Smoke Simulation. It seems to work now. I have lots of smoke! Thanks!
