 Now, we can focus on the trackers that contribute most on each end of the scale.
 I'm still searching for a better visualisation though, and I think we can keep the colours, but use their absolute loading value to plot.
 This will place all the most important components in order at the very left of the plot, and we can distinguish between positive and negative by their colour.

 I'm using the [ggsankey](https://github.com/davidsjoberg/ggsankey) package by [David Sjoberg](David Sjoberg) here, which is _not_ on CRAN, but I think makes the most beautiful Sankey diagram
 (hint hint David, get it on CRAN, will ya?).
