According to some embodiments, an event query to an item supply chain event database is processed such that a trace extraction algorithm will be executed to determine extracted trace data. A plurality of location nodes may then be graphically represented on an interactive user display based on the extracted trace data. Similarly, a plurality of item flow edges connecting location nodes may be graphically represented on the interactive user display based on the extracted trace data. According to some embodiments, a selection from a user is received via the interactive user display, the selection being associated with at least some of the graphically represented information. Responsive to the received selection, the graphical representation may be adjusted in accordance with the extracted trace data.
