A three-dimensional (3D) view of a data collection based on an attribute is disclosed.
A timeline is provided for displaying files and folders. The timeline may include
a focal group that displays detailed information about its contents to the user.
Remaining items on the timeline are displayed in less detail and may be positioned
to appear further away from the user. A histogram may be provided as part of the
view to allow the user to more easily navigate the timeline to find a desired file
or folder.
