We present the results of a study comparing five directed-edge representations for use in 2D, screen-based node-link diagrams. The goal of this work is to extend the understanding of tradeoffs and best practices for the representation of edges in directed graphs and to help practitioners choose among different options. Our work applies to graphs in which directed links are depicted using lines connecting the nodes. We tested five different edge representations chosen carefully based on user… Expand
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
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

  • 2016
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
Animated Edge Textures in Node-Link Diagrams: a Design Space and Initial Evaluation
TLDR
This work introduces a design space and Web-based framework for generating animated edge textures, and reports on an initial evaluation of particle properties - particle speed, pattern and frequency - in terms of visual perception. Expand
Edge Compression Techniques for Visualization of Dense Directed Graphs
TLDR
This work explores the effectiveness of visualizing dense directed graphs by replacing individual edges with edges connected to 'modules'-or groups of nodes-such that the new edges imply aggregate connectivity, and proposes a novel optimal technique based on constraint programming. Expand
INSTITUT FÜR INFORMATIK Edge Label Placement in Layered Graph Drawing
Many visual languages based on node-link diagrams use edge labels. We describe different strategies of placing edge labels in the context of the layered approach to graph drawing and investigate waysExpand
The Impact of Visual Aesthetics on the Utility, Affordance, and Readability of Network Graphs
TLDR
The results show differential readability effects among choices of visual aesthetics, and node based visual encoding significantly enhances network readability; specifically, glyphs allow participants to create more robust strategies in their utilization. Expand
Unfolding Edges
With this research we present an approach to network visualization that expands the capabilities for visual encoding and interactive exploration through edges in node-link diagrams. Compared to theExpand
Radial Edge Splatting for Visualizing Dynamic Directed Graphs
TLDR
A novel radial version of a scalable dynamic graph visualization thatodes dynamic directed graphs on narrow rings of a circle and illustrates the usefulness of the diagrams by applying them to call graph data of the open source software project Cobertura. Expand

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
Motion to support rapid interactive queries on node--link diagrams
TLDR
A set of techniques that use motion in an interactive interface to provide effective access to larger graphs and argue that motion highlighting can be a valuable technique in applications that require users to understand large graphs. Expand
A user study on visualizing directed edges in graphs
TLDR
Five additional directed-edge representations using combinations of shape and color are developed and a user study is performed in which subjects performed different tasks on a collection of graphs using these representations and combinations to investigate which representation is best in terms of speed and accuracy.

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
A Comparison of the Readability of Graphs Using Node-Link and Matrix-Based Representations
TLDR
It is shown that when graphs are bigger than twenty vertices, the matrix-based visualization performs better than node- link diagrams on most tasks, and only path finding is consistently in favor of node-link diagrams throughout the evaluation. 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
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

TLDR
This study widens the scope of readability comparisons between node-link and matrix-based representations by introducing new user tasks and replacing simulated, undirected graphs with directed ones employing real-world semantics. 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
