This is a timeline visualization of surfing activity recovered from Internet Explorer cache index.dat files. The graph was generated with the SIMILE Timeline Widget AJAX API. The graph has two timeline bands: The bottom one gives an overview of the activity over the complete timeline and the top one shows the details. The graph can be interactively navigated by panning the graph right/left. Different magnification levels can be set for each timeline band and also within a timeline.
Extraction from the index.dat files was done with Pasco. With awk/sed and some manual tweaking the data was transformed to a XML that can then be visualized with the API.
