Graphs are often visualized using node-link representations: vertices are depicted as dots, edges are depicted as (poly)lines connecting two vertices. A directed edge running from vertex A to B is generally visualized using an arrow representation: a (poly)line with a triangular arrowhead at vertex B. Although this representation is intuitive, it is not guaranteed that a user is able to determine edge direction as quickly and unambiguously as possible; alternative representations that exhibit… Expand
A User Study on Curved Edges in Graph Visualization
TLDR
Two experiments studying the impact of edge curvature on graph readability show significant performance differences between the straight and curved edges and clear distinctions between variations of curved edges. Expand

Partial Link Drawings for Nodes, Links, and Regions of Interest
Partially drawn links in graph visualizations have been introduced as a concept for further reducing visual clutter caused by many link crossings in combination to a formerly applied layout algorithmExpand
Performance Evaluation of Tapered, Curved, and Animated Directed-Edge Representations in Node-Link Graphs
We present the results of a study comparing three directed-edge representations in node-link diagrams. Node-link diagrams are probably the most popular type of graph representations; nodes areExpand
Evaluating Partially Drawn Links for Directed Graph Edges
TLDR
It is found that partially drawn links can lead to shorter task completion times, which occurs for nearly all graph sizes, tasks, and both tapered and traditional edge representations, which in fact is task-dependent. Expand
Exploring density regions for analyzing dynamic graph data

TLDR
A novel dynamic graph visualization that is based on the concept of smooth density fields generated by first splatting the link information of a given graph in a certain layout or visual metaphor is described, and the user can automatically apply region comparisons with other graphs based on global and local density properties.

TLDR
This paper describes a novel dynamic graph visualization that is based on the concept of smooth density fields generated by first splatting the links of a given graph in a certain layout and adds user-adaptable isolines to the resulting dynamic graph representation. Expand
Dynamic Graph Visualization with Multiple Visual Metaphors
TLDR
This paper shows an idea to solve the problem of using multiple visual metaphors for dynamic graphs which are computed automatically by algorithms analyzing each individual graph based on a given repertoire of graph features. Expand
Visual analytics of large dynamic digraphs
TLDR
This work focuses on achieving an overview about long graph sequences with the major focus to be scalable in vertex, edge, and time dimensions, and applies edge splatting as a concept to emphasize graph structures by color coding the generated density fields. Expand
Supporting graph editing in visual representations
TLDR
An approach for providing navigation recommendations to interesting data is presented additionally and the concept of lenses is investigated and the applicability and suitability of the approaches developed within this thesis is demonstrated with several use cases. Expand

Hierarchical Edge Bundles: Visualization of Adjacency Relations in Hierarchical Data
  • Danny Holten
  • Computer Science, Medicine
  • IEEE Transactions on Visualization and Computer Graphics
  • 2006
TLDR
This paper presents a new method for visualizing compound graphs based on visually bundling the adjacency edges, i.e., non-hierarchical edges, together and discusses the results based on an informal evaluation provided by potential users of such visualizations. Expand
Overlaying Graph Links on Treemaps
TLDR
A visualization technique that displays the tree structure as aTreemap and the remaining edges as curved links overlaid on the Treemap to show where the link starts and where it ends without requiring an explicit arrow that would clutter the already dense visualization. Expand
Edgelens: an interactive method for managing edge congestion in graphs
TLDR
The EdgeLens interactively curves graph edges away for a person's focus attention without changing the node positions, which opens up sufficient space to disambiguate node and edge relationships and to see underlying information while still preserving node layout. Expand
Supporting Visual Queries on Medium-Sized Node–Link Diagrams
TLDR
An interactive technique whereby a subset of a larger network diagram is highlighted by being set into oscillatory motion when a node is selected with a mouse, designed to support visual queries on moderately large node-link diagrams containing up to a few thousand nodes is described. Expand

TLDR
From around 1990 onwards, increased attention has been paid to interactive, or dynamic visualization of Network Data, and these techniques have surfaced in a variety of different fields, including Statistical Graphics, Information Visualization, and many applied areas. Expand
Visualizing graphs in three dimensions
It has been known for some time that larger graphs can be interpreted if laid out in 3D and displayed with stereo and/or motion depth cues to support spatial perception. However, prior studies wereExpand
Dynamic visualization of graphs with extended labels
TLDR
A novel technique to visualize graphs with extended node and link labels that shares the visualization resources with the graph and presents the label information in static, interactive, and dynamic modes without the requirement for tackling the intractability issues. Expand
Just how dense are dense graphs in the real world?: a methodological note
TLDR
This methodological note focuses on the edge density of real world examples of networks, and draws a list of conclusions on how to tune edge density when randomly generating graphs in order to build artificial though realistic examples. Expand
Thoughts on User Studies: Why, How and When
TLDR
The main goal is to encourage the use of studies in visualization, but it is recognized that other disciplines also offer important insights into visualization design, for example, the areas of visual design or the visual arts. Expand
