         * I spent some time poking around, and the simplified 50m map units data ended up being mostly sufficient. I say "mostly" because some regions that Yakko mentions aren't included, and I didn't have enough expertise with manipulating either NaturalEarth's shapefiles or GEOJson to hand pick targets from several datasets, and even if I did some of these places don't exist as logical units any more so I'd still have to come up with some further solution. To solve targeting for the 9 problem regions (San Juan, Czech Republic, Tibet, Sumatra, Yugoslavia, Algiers, Dahomey, Transylvania, Crete), I just picked out replacement regions to target instead. For example, when the code decides it's time to target Yugoslavia, then Serbia, Montenegro, Macedonia, Slovenia, Serbia, Croatia, Kosovo, Bosnia, and Herzegovina get targetted instead. This logic is the first part of the `targetCountry` function.
         * It's not a particularly brilliant solution but it was simple enough and worked so I could move on
         * Ultimately I was amazed how (relatively) easy it is to go from no data to a globe. Mike Bostock's [Let's Make A Map](http://bost.ocks.org/mike/map/) tutorial is a great place to start, along with installing topojson and experimenting with the parameters. Nate Kelso's [Natural Earth](http://www.naturalearthdata.com/) datasets are and invaluable resource that makes getting started very simple.

 * Step 7
     * Finally, set this up on my website with using a layout and stylesheets from previous visualizations, write the description text, set up comments and so forth.
