Glidgets: Interactive Glyphs for Exploring Dynamic Graphs
نویسندگان
چکیده
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.

Glyphs for Exploring Crowd-sourced Subjective Survey Classification
The findings drawn from opinion survey responses are usually made by producing summary charts or conducting statistical analysis. Both involve data aggregation and filtering as exploring the unaggregated data has traditionally been impractical or error-prone for large numbers of responses. We propose the use of glyphs with parallel coordinate plots to show all survey responses in a single view ...
متن کاملAgglomerative Clustering of Growing Squares
We study an agglomerative clustering problem motivated by interactive glyphs in geo-visualization. Consider a set of disjoint square glyphs on an interactive map. When the user zooms out, the glyphs grow in size relative to the map, possibly with different speeds. When two glyphs intersect, we wish to replace them by a new glyph that captures the information of the intersecting glyphs. We prese...

This note o ers a reflection on the design space for a situated glyph a single, adaptive and multivariate graphical unit that provides in-situ task information in demanding work environments. Rather than presenting a concrete solution, our objective is to map out the broad design space to foster further exploration. The analysis of this design space in the context of dynamic work environments c...
متن کاملGarneau, The use of humanoid glyphs in graphs The use of humanoid glyphs in graphs for representing human variability in the spatial design of products
From simple color-coding to more intricate forms like the “Chernoff face”, glyphs are a means of visualizing multidimensional data. The spatial design of products for their users presents a unique opportunity for using glyphs as a visual metaphor for encoding data, chiefly due to the multivariate nature of many commonly encountered problems. While relatively intricate glyphs called “Digital Hum...
متن کاملInteractive Glyph Placement for Tensor Fields
Visualization of glyphs has a long history in medical imaging but gains much more power when the glyphs are properly placed to fill the screen. Glyph packing is often performed via an iterative approach to improve the location of glyphs. We present an alternative implementation of glyph packing based on a Delaunay triangulation to speed up the clustering process and reduce costs for neighborhoo...
