# == Description
#
# Creating a scatterplot with statsample's Statsample::Graph::Scatterplot class.
# 
# In this example we'll demonstrate how a normally distributed Daru::Vector can
# be created using the daru and distribution gems, and how the values generated
# can be plotted very easily using the 'scatterplot' shorthand and supplying X
# and Y co-ordinates.
