Various systems and methods are provided for accessing and traversing one or more complex data structures and generating a functional user interface that can enable non-technical users to quickly and dynamically generate detailed reports (including tables, charts, and/or the like) of complex data including time varying attributes and time-series data. The user interfaces are interactive such that a user may make selections, provide inputs, and/or manipulate outputs. In response to various user inputs, the system automatically calculates applicable time intervals, accesses and traverses complex data structures (including, for example, a mathematical graph having nodes and edges), calculates complex data based on the traversals and the calculated time intervals, displays the calculated complex data to the user, and/or enters the calculated complex data into the tables, charts, and/or the like. The user interfaces may be automatically updated based on a context selected by the user.
