This timeline is similar to a Google Map: it imports data from an XML file, so it's easy to visualize temporal information, like the evolution of a company, a person or an event. There is also a step-by-step guide that helps you create a timeline.
The widget was created by Simile (Semantic Interoperability of Metadata and Information in unLike Environments), a group that develops open source tools related to Semantic Web. You can find other interesting tools at their website.
