Timeplot is a DHTML-based AJAXy widget for plotting time series and overlay time-based events over them (with the same data formats that Timeline supports). The original site is: http://simile.mit.edu/timeplot/
I’ve installed it and make a couple of very simple tests, the installation is very simple and the XML-based language to feed the graphical interface very intuitive here is an example.
Here follows a simple example of XML input file:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<event start="Jan 01 1849 00:00:00 GMT" title="California Gold Rush" link="http://en.wikipedia.org/wiki/California_Gold_Rush"></event>
<event start="Apr 12 1861 00:00:00 GMT" end="Apr 09 1865 00:00:00 GMT" title="American Civil War" link="http://en.wikipedia.org/wiki/American_Civil_War"></event>
