visualization process is view navigation. Chaomei Chen2 stated in his book that ‘navigation in a hierarchical structure involves moving from one node to another, along the existing hierarchical links in the structure. When the size of a hierarchy becomes large, it is desirable to enable users to have easy access to contextual. visualization technique makes % use of the available display space, mapping the full hierarchy onto a rectangular region in a space-filling manner. This efficient use of space allows very large hierarchies to be displayed in their entirety and facilitates the presentation of semantic information. 1 Introduction.

a given visualization technique must strive to provide both local detail and global context [2,4,5,6,7]. The goal of these visualization techniques is not limited to only providing focus and context. Other desirable features would include allowing users to select multiple foci [6] or providing the user with multiple detailed views. Focus+Context visualization niques developed to visualize graphs and hierarchies include the Continuous Zoom [1], the Hyperbolic Tree ear magnification fields [13], multiple dimensions of transformation [26], and higher-order visualizations [5], or by describing them as interactive externalizations [28].

Visualisation and navigation of large hierarchies with multiple foci and context approach by Hongzhi Song Download PDF EPUB FB2

Multiple foci are consistently accessible within a global context through interaction. Furthermore it can handle a large hierarchy that conta nodes in a PC environment.

This technique has. Visualisation and navigation of large hierarchies with multiple foci and context approach Author: Song, Hongzhi. ISNI: Awarding Body: University of Ulster Current Institution: Ulster University Date of Award: Availability of Full Text.

hierarchies without losing global context, and making it difficult to focus on multiple nodes because of the distance between them. In contrast, by showing paths (rather than expanded subtrees), we are able to scale up to enormous hierarchies while supporting multiple foci.

The user interface, as shown in Figure 1, has four by:   We propose a holistic approach for the presentation of large hierarchies using treemaps and progressive refinement.

The key feature of the approach is the mature use of multiple incremental previews of the data. These previews are well-designed and lead to reduced visual clutter and a causal flow in terms of a by: 8.

(eds) Human-Computer Interaction – INTERACT INTERACT Lecture Notes in Computer Science, vol Springer, Berlin. The most commonly used interaction techniques in space-filling visualization are drilling-down + semantic-zooming and focus + context methods.

However, under these schemes, users often have insufficient knowledge about contextual information to guide them exploring through very large and deep hierarchical structures. This paper proposes an efficient interaction method called “chain-context.

Exploring large hierarchies is still a challenging task, especially for handheld tactile devices, due to the lack of visualization space and finger’s occlusion.

In this paper, we propose the RICHIE (Radial InCremental HIerarchy Exploration) tool, a new radial widget that allows step-by-step navigation through large hierarchies. of that visualization found that the technique did not scale well and abandoned the approach.

The polyarchy visualization technique does scale to very large hierarchies, as will be discussed. MultiTrees [6] are multiple hierarchies with shared subtrees.

But polyarchies are multiple intersecting hierarchies, sharing at least one node rather. 3 Hierarchical Data Representation Special type of graph (tree): G={V,E} – Acyclic (no loop or cycle) – Rooted – Each sub-graph is also a tree Challenging for large. Besides the layout algorithm, EncCon uses a new focus+context viewing technique for the navigation of large hierarchies.

We use the zooming+layering concept to achieve the focus+context viewing, rather than the traditional enlarge+embedded concept which is used by most of the available focus+context techniques.

Focus+Context Visualization Focus+context visualization attempts to maximize the use of display space by depicting information of interest at a higher resolution/larger size than that of contextual information. For this work, focus+context methods for graph and hierarchy visualization.

To be able to handle the navigation of large hierarchies, we use a new hybrid viewing technique that combines two viewing methods, the modified semantic zooming and a focus+context technique.

In this approach, we link a dynamic 3D focus+context visualization with a 2D chart of time series data to guide the detection and navigation towards important spatio‐temporal events.

Introduction. A vast quantity of visualization tools has emerged over the past decade as a response to the need for analyzing large, unstructured data sets, particularly in the field of Biology [].The data sets that are often the target of modern research in the field of computational biology are often complex because of possessing multiple characteristics found in ‘big data’.This chapter details different types of navigation in the classic book on information architecture.

The authors define slightly different types of navigation than those presented here, but the same principles apply. Also included in this chapter are good discussions of site maps, site indexes, visualization, and social navigation.

In the OnionGraph visualization, the focused sub-network is expanded in-situ by the focus+context principle. The network view in the middle can juxtapose sub-networks with multiple hierarchy settings. This is quite different from the overview+detail network visualization and the hierarchy-traversing navigation that do not preserve context.
