Data issues?

[dannguyen]

In the All.json file, there are numerous entries categorized as '930330', which doesn't appear to be used in the actual visualization. e.g.:

    {
          "i": "Paraguay",
          "wc": "930330",
          "e": "Argentina",
          "v": 7225
      }

Also, a better explanation of what the data actually represents (and doesn't include) would be helpful (the sources linked to are either down or don't really say much on it)...for example, exports of military weapons from America to Pakistan:

Year	Military exports
1997	11018500
1998	blank
1999	45839
2000	4800

Besides the blank in 1998, the number in 2000 ($4,800) seems artificially low, as if we exported only 50 guns. There are even smaller, specific numbers and stranger year to year jumps, not easily explained by geopolitics (i.e. war on terror). When the data is in a spreadsheet, it doesn't make much sense.
