Using seaborn library you can do something like this:

import seaborn
import pandas as pd

csvfile = "C:/Users/Simon/Desktop/test.csv"

data = pd.read_csv(csvfile)

fg = seaborn.factorplot(x='ID', y='Values', hue='GroupName', kind='bar', data=data)

That will get you something like this:

In my example data is a dataframe created by reading a csv file, but this will work regardless of how you got your data in, as long as its a dataframe
