Is raising an exception the right choice here -- why can't we plot an
all zeros image?

When sparse matrices have explicit zero values, `axes.spy` plots those
zero values. This behavior seems unintentional. For example, the
following code should have a main diagonal with markers missing in the
middle, but `spy` currently plots a full main diagonal.
