Issue 673: Add title and just year as x-axis label

Issue #673

Extract the years from the columns (so instead of gdpPercap_<year> will just be the year), and add title to the plot as GDP Per Capita for Regions Over Time.

Thanks. This change to the suggested solution is not directly visible in the workshop material but if one downloads the code and generates the graph one will see be a substantial improvement: avoiding ugly overlapping x-labels. There is nothing to question here so I will accept it.
