Re: [Matplotlib-users] Are matplotlib paths equivalent to svg paths?

[Jason M. <moo...@gm...>]

Actually the notation I have is valid SVG path data. Your script could be
modified to handle the more general forms, see:

http://www.w3.org/TR/SVG/paths.html#PathDataGeneralInformation

But this still doesn't answer why the smoothness is different between the
SVG and matploblib paths. I haven't been able to figure that out yet.
