• John Snow’s Famous Cholera Map

    September 12, 2007  |  Mapping

    John Snow Cholera MapIf you've read any books on visualization, without a doubt, you've seen John Snow's now famous cholera map. In 1854, people were dying in large numbers and high frequency, but nobody knew what was going on. John Snow solved the mystery with his map.

    It's crazy to imagine a time when people didn't think to map data, especially now as mapping data has become second nature for some. Steven Johnson, author of Ghost Map, goes into depth on the Cholera outbreak in London in his book and TED talk earlier this year.

    I'd embed it, but I can't find the link anywhere on the TED page. They probably had to make it less obvious after Hans Rosling's talk spread at the speed of Cholera in London in 1854. London hasn't had another outbreak since Snow's simple (for this day and age) but effective visualization.

    UPDATE: Here's Steven Johnson's TED talk

  • More Mapping from amMap Offering Flexibility

    July 13, 2007  |  Mapping, Online Applications

    amMap

    Yes, more mapping. Map, map, map. amMap offers a Flash-based mapping tool that you can download and customize to your liking.

    Ammap is an interactive flash map creation software. Use this tool to show locations of your offices, routes of your journeys, create your distributor map. Photos or illustrations can be used instead of maps, so you can make different presentations, e-learning tools and more.

    There's some smooth browsing and zooming, and it's pretty sleek. Those who appreciate simplicity will appreciate amMap. Plus, it's free :) Continue Reading

  • History Over Space and Time

    Maps of War

    As a representation of history over time and space, Maps of War does a pretty good job of displaying the information in the form Flash animations. It's quite simple really. The animation starts centuries back (e.g. 2000BC) and moves to geographic regions. In the above map, I watched who has controlled the middle east, beginning 3000BC up through 2006.

  • Twittervision Adds a Third Dimension

    Twittervision 3D

    Twittervision is a Google Maps mashup using the Twitter RSS feed. As people post to Twitter, you see the map move from location to location all around the world. It's really simple, but there's something entertaining about it that I can't quite put my finger on. Maybe we just like to peak into other people's lives. Anyways, I don't know how recent this is, but Twittervision now has a third dimension which is equally as entertaining as the original.

    Akamai: Network Performance Comparison

    Akamai is a technology company that deals with routing and online business. They optimize routing over the Internet using the data they collect from servers setup in 71 countries. Or I guess, in their words

    Akamai's technology – at its core, applied mathematics and algorithms - has transformed the chaos of the Internet into a predictable, scalable, and secure platform for business and entertainment. The Akamai EdgePlatform comprises 20,000 servers deployed in 71 countries that continually monitor the Internet – traffic, trouble spots and overall conditions. We use that information to intelligently optimize routes and replicate content for faster, more reliable delivery. As Akamai handles 20% of total Internet traffic today, our view of the Internet is the most comprehensive and dynamic collected anywhere.

    Wait, that's not the good part. They use Flash-based visualization to display how good they really are. I did a network performance comparision for a route from New York to Hong Kong, and in turn, the viz showed the public internet path and a much-improved Akamai path. Less packet loss and lower latency for Akamai. It'd be interesting to know how those routes are depicted, because I imagine, the routes aren't really always straight line vs parabola, Akamai vs public internet. Very pretty though.
