Timelines are as important for presenting temporal data as node-link diagrams are relevant for displaying graphs and relations in general. Yet, both are rarely combined. We present Time Shadows to precisely indicate a node's place in time, revealing associated temporal data and relations. We also introduce Time Beads. Created as a focus and context interaction technique for time-based graphs, Time Beads allow to continuously or discretely change the level of detail and to set multiple arbitrary focus regions if needed. We implemented both techniques in a prototype and conducted an initial user study.
