A system, method, and computer program product for selecting, processing, and visually depicting information in real time using in-memory technology and user-customizable Sankey diagrams in a graphical user interface. Embodiments receive data describing contact interactions with a business establishment, select interactions occurring frequently during a given time span that led to selected target events, and aggregate similar interaction sequences into paths displayed with widths denoting relative flow quantities. Embodiments modify the depicted information according to user customization of the Sankey diagram. Coherent coordination of visual depiction by context, associated algorithms and models, data sources, event types, and various graphical indicia helps provide an intuitive exploratory situational overview and enables user-driven detailed investigations of complex data via manipulations of the Sankey diagrams. Business assessments and properly directed business actions may improve marketing campaign and customer service effectiveness and increase return on investment without requiring extensive user training or database expertise.
