Before building any cartogram, you need to understand how to build a basic map background. When dealing with grouped data, you will often want to have various summary statistics computed within groups; for example, a table of means and standard deviations. So, before you actually make the plot, try and figure what findings and relationships you would like to convey or examine through the visualization.
