Ideally, I could do it on MapPoint, but I don't think it's possible. Does anyone have any suggestions on how to create a map showing connections between departure airports and destination airport? Actual flight pattern isn't necessary, just connection between two points (airports) with a strait line or preferable a gentle arc.

Recently it has <a href="http://www.fivethirtyeight.com/2009/05/debunking-so-called-human-development.html" rel="nofollow">come under fire</a> because the color coding causes it to misrepresent the differences between states. That is, Mississippi is colored yellow and WV colored light green even though their difference is 0.001.</p> <p>My first question would be what is the best way to make this map? If it were up to me, with my limited knowledge, I would grab this <a href="http://commons.wikimedia.org/wiki/File:BlankMap-USA-states.PNG" rel="nofollow">blank map from wikipedia</a>, make up some bins (.75-.79, .80-.85, etc.) and a color scheme, fire up an image editor and just colorfill the different sections. Is there a better way?</p> <p>What about the color difference problem between MS and WV? My first instinct would be to just map the values from maybe .750 - 1.000 onto a 8-bit (255 value) color scheme and calculate a color value for every state. Would that be the right approach?</p> <p>Thanks,<br /> Sachin </p> http://forums.flowingdata.com/topic/death-penalty-around-the-world#post-678 Sun, 03 May 2009 13:11:27 +0000 nathany 678@http://forums.flowingdata.com/ <p>Here's another interesting graphic from GOOD Magazine's transparency section.</p> <p><a href="http://www.good.is/post/transparency-the-death-penalty-around-the-world/" rel="nofollow">http://www.good.is/post/transparency-the-death-penalty-around-the-world/</a></p> <p>I have yet to see a GOOD sheet in my local Starbucks.
