“…McGuffin and Jurisica's approach lets users modify a node‐link diagram by applying a chosen layout algorithm on a selected subset of nodes [MJ09]. In contrast, MagnetViz [SF12] allows users to reorganize the entire diagram through virtual magnets that attract nodes.…”

International audienceNode-link infographics are visually very rich and can communicate messages effectively, but can be very difficult to create, often involving a painstaking and artisanal process. In this paper we present an investigation of node-link visualizations for communication and how to better support their creation. We begin by breaking down these images into their basic elements and analyzing how they are created. We then present a set of techniques aimed at improving the creation workflow by bringing more flexibility and power to users, letting them manipulate all aspects of a node-link diagram (layout, visual attributes, etc.) while taking into account the context in which it will appear. These techniques were implemented in a proof-of-concept prototype called GraphCoiffure, which was designed as an intermediary step between graph drawing/editing software and image authoring applications. We describe how GraphCoiffure improves the workflow and illustrate its benefits through practical examples.

“…The group has started to work with social networks as an experimental area for graph visualization techniques. A technique (and tool) named MagnetViz [3] was designed for the interactive manipulation of force-directed graph layouts, allowing users to obtain visualizations based on the graph topology and/or the attributes of its nodes and edges. Users can introduce virtual magnets anywhere in the layout and these can be set to attract nodes and edges that fulfill user-defined criteria.…”

The Computer Graphics, Image Processing and Interaction (CGIP) group at UFRGS concentrates expertise from many different and complementary graphics related domains. In this paper we introduce the group and present our re- search lines and some ongoing projects. We selected mainly the projects related to 3D interaction and navigation, which includes applications as massive data visualization, surgery planning and simulation, tracking and computer vision algorithms, and modeling approaches for human perception and natural world.

“…The original nested model focuses on providing guidance in terms of choosing appropriate validation techniques at each level and stresses the negative and cascading implications of poor design decisions. It has provided guidance, motivation, framing, and ammunition for a broad range of visualization papers, including problem-driven design studies, [20][21][22][23][24][25] technique-driven work, 26 evaluation, 27,28 models, 3,[29][30][31][32][33][34] and systems. 35,36 While we and others have used the nested model extensively as a way to guide decisions about evaluation and design, we have found that it falls short in capturing and describing design decisions at the level of detail needed for thorough analysis.…”

We propose the nested blocks and guidelines model (NBGM) for the design and validation of visualization systems. The NBGM extends the previously proposed four-level nested model by adding finer grained structure within each level, providing explicit mechanisms to capture and discuss design decision rationale. Blocks are the outcomes of the design process at a specific level, and guidelines discuss relationships between these blocks. Blocks at the algorithm and technique levels describe design choices, as do data blocks at the abstraction level, whereas task abstraction blocks and domain situation blocks are identified as the outcome of the designer's understanding of the requirements. In the NBGM, there are two types of guidelines: within-level guidelines provide comparisons for blocks within the same level, while between-level guidelines provide mappings between adjacent levels of design. We analyze several recent papers using the NBGM to provide concrete examples of how a researcher can use blocks and guidelines to describe and evaluate visualization research. We also discuss the NBGM with respect to other design models to clarify its role in visualization design. Using the NBGM, we pinpoint two implications for visualization evaluation. First, comparison of blocks at the domain level must occur implicitly downstream at the abstraction level; and second, comparison between blocks must take into account both upstream assumptions and downstream requirements. Finally, we use the model to analyze two open problems: the need for mid-level task taxonomies to fill in the task blocks at the abstraction level, as well as the need for more guidelines mapping between the algorithm and technique levels.
