Animated Graphs from 9/11
The data from September 11 2001 show a number of departures from random expectation. Here we present three animated graphs that show the development of various measures over time, along with a "baseline" graph that displays typical random data. It takes a few seconds for the data drawing to begin after the graph frame is presented. The animations were created by Greg Nelson, using Perl scripts and Gifsicle, a powerful Unix/Linux program for manipulating GIF files.
