This looks like the path simplification bug that was fixed some time
before mpl 1.0. You can upgrade, or as a workaround you can turn off
path simplification by putting
path.simplify : False
in your matplotlibrc file, or by using
matplotlib.rcParams['path.simplify'] = False
in your script.

Beautiful is writing same markup. Internet Explorer 9 supports
standards for HTML5, CSS3, SVG 1.1, ECMAScript5, and DOM L2 & L3.
