Anyone knows my past research will know me as a researcher in information visualization, but the reality is that there has been very few good information visualization techniques that really work. One of those is the SmartMoney Map of the Market visualization app that looks at the performance of the stock market, and gives you at a glance the performance of different sectors of the market.
NYTimes is one of the few news outlets that really does a good job with their graphics, and recently the director of their graphics dept. gave a keynote address at the Infovis2007 conference, and I found many of their visualizations to be very interesting and informative. One of these visualizations is the words and speeches visualization they created on President Bush's addresses.
