Abstract: We present Glidgets, a combined direct manipulation and visualization technique for exploring and querying changes of elements in dynamic graphs. Traditional approaches provide an indirect time slider and employ visual cues such as global \ change highlighting. Our work merges temporal navigation and the visual \ representation of graph dynamics into interactive visual glyphs on nodes and edges. Our time line glyphs reveal the presence and absence of graph elements, \ and node degree. Using sketch-based interaction, the glyphs are used to create queries and navigate time directly on graph nodes and edges. This enables one-stroke gestures to answer questions such as ``Are these nodes ever connected?'' or ``When is this node present in the network?'' Analysts can directly query changing graph elements and investigate those changes by navigating time, while focusing on the element.
