Dynamic Flash app tracks market activity

John Caserta sent this link to a site he designed (as part of a team) for The New York Times. It’s a really nice example of how to visually represent data with a back-end application that updates the numbers as needed. Companies within a selected market sector are represented by dots. The bigger the dot, the larger the market cap. The visualization is divided into quadrants that represent month/year and behind/ahead of the S&P 500. Check out the Help screen (linked at top right) if you’re not a finance wizard — or even if you are. It’s a first-rate example of clear and useful help for how to use and understand the chart.
