pygal.Line() render_to_file: OverflowError: cannot convert float infinity to integer

I'm still trying to isolate a testcase, but I'm seeing this with a particular dataset:

File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/graph/public.py", line 114, in render_to_file
    f.write(self.render(is_unicode=True, **kwargs))
  File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/graph/public.py", line 52, in render 
    self.setup(**kwargs)
  File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/graph/base.py", line 217, in setup 
    self._draw()
  File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/graph/graph.py", line 926, in _draw 
    self._compute_y_labels()
  File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/graph/graph.py", line 853, in _compute_y_labels
    self.order_min, self.min_scale, self.max_scale
  File "/opt/local/python-3.6.1/lib/python3.6/site-packages/pygal/util.py", line 163, in compute_scale
    order = round(log10(max(abs(min_), abs(max_)))) - 1
OverflowError: cannot convert float infinity to integer

FYI, this does appear to be an input data issue. I was plotting data from pandas, and one of the cells was inf causing this error. I'm not sure if something more graceful can be done here.
