Here are Mike's comments and mine:
Why it's bad:First, to see the detail you have to click on the countries one by one. Hard to do a comparison of two countries. This makes it close to FlashJunk.
The color scheme is supposed to help but:
Second, the colors are too close together to allow easy comparisons of, say, Canada and Australia.
In addition, the binning of the colors is uneven and oddly chosen. In the middle of the scale, each color shift represents 1% but at the edge, it is 5%, or more.
Third, area of these countries, or their geographic location, isn't really that relevant. Market cap might be. Then tiny-but-richly-capitalistic
Netherlands wouldn't have to be shown in the middle of the Atlantic, as if the dikes had all burst and Amsterdam had floated out to sea.
Fourth, why the selectivity? There's stock markets in Turkey, and in Russia, and in Ireland and in Thailand. (Oh, wait, they show the one in Thailand -- except they put it in Myanmar instead.)
Finally, the chart lacks a punch line.
In the junkart version, I want to test the hypothesis of a global contagion so I plot the data in order of closing times of individual stock markets. (I just guessed the closing times based on the map.) Not much here though.
