Note for Developers : Because of Flash security settings, this (and all Flash-based visualizations) might not work correctly when accessed from a file location in the browser (e.g., file:///c:/webhost/myhost/myviz.html) rather than from a web server URL (e.g., http://www.myhost.com/myviz.html). This is typically a testing issue only.
