Yes.  Please take a look at gnuradio-examples/python/usrp/*.py

Not sure what you mean by "view a graph".  
We're using graph as in vertices and edges, not graph as in power point.

You can generate documentation by:

  $ cd gnuradio-core
  $ ./configure --enable-doxygen
  $ make

Then point your browser at gnuradio-core/doc/html/index.html

Click on "Class Hierachy".  All the signal processing blocks are
derived from gr_block

This is out of date, but will give you an idea:
