"Creating a scatterplot with statsample's Statsample::Graph::Scatterplot class.\n",
" \n",
"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.\n",
