The problem is that the Polygon module for Python isn't installed.
That's one of the dependencies. As it says in INSTALL.txt, "For Visual
5.3 and later, you need the Python modules FontTools, ttfquery, and
Polygon. Be sure to get ttfquery 1.0.4 or later."
However, the only object affected by the absence of the Polygon (and
FontTools and ttfquery modules) is the 3D text object, so if you don't
need to use the text object, and you don't want to go to the trouble
of satisfying the dependencies, you could comment out the imports of
these modules in visual/visual_all.py, vis/__init__.py, and
vis/primitives.py. In fact, I'm working on a new version of Visual
which will among other things in the absence of these modules give a
warning that you can't use the text object but you can do everything
else.
