An embodiment of a user interface of an electronic device is configured to display user interface elements along a timeline. Each displayed user interface element is associated with an event that is characterized by one or more event attributes. The event attributes include a temporal attribute (e.g., a date and/or time). Each user interface element is relatively positioned along the timeline based on its temporal attribute, and each user interface element is displayed with a visual representation of a set of its associated event attributes. The displayed set of event attributes for a particular user interface element is determined based on a position of the user interface element along the timeline and/or a spatial zoom level at the time. The spatial zoom level and/or position along the timeline of each user interface element may be modified based on user inputs.
