"""
Plotting simple quantities of a pandas dataframe
=================================================

This example loads from a CSV file data with mixed numerical and
categorical entries, and plots a few quantities, separately for females
and males, thanks to the pandas integrated plotting tool (that uses
matplotlib behind the scene).

See http://pandas.pydata.org/pandas-docs/stable/visualization.html
