Title: Chapter 6 added fig 6.4 & 6.5

I also included a version of plot 6.5 using rCharts, which allows you to toggle off the countries and view the data values / legend interactively. If we are ok adding rCharts to the list of dependencies then I would like to remake more of the plots in this framework.
