No figure output of the show method and produce a lot of findfont: Generic family 'sans-serif' not found warnings about yellowbrick

[bingyao]

It seems that many methods will produce the findfont warning messages:

findfont: Generic family 'sans-serif' not found because none of the following families were found: Arial, Liberation Sans, Bitstream Vera Sans, sans-serif
findfont: Generic family 'sans-serif' not found because none of the following families were found: Arial, Liberation Sans, Bitstream Vera Sans, sans-serif
...

and I am not sure why the instantiation of a ResidualsPlot visualizer also produce and rendering an empty figure (showing in the screenshot):

visualizer = ResidualsPlot(LinearRegression())

Hi @bingyao - thank you for using yellowbrick! It appears that the issue you are experiencing has to do with matplotlib rather than yellowbrick and is typically experienced by users who are on a Linux OS.
