The idea is to use a graphical representation to represent an information space, e.g. a complex concept, a WebSite or parts of the Web as a whole, user activities ....
DSchneider doesn't know if we should split this up like for example the Wikipedia:Visualization article (and add multimedia animations which are not necessarily the same as what they call Wikipedia: Knowledge visualization).
2 Types of visualizations
Lloyd Rieber (2002) categorizes visualizations according to their physical characteristics.
- representational - resemble the object represented ranging from realistic (photographs) to simplified lines and shapes.
- analogical - using a representation of an object with similar qualities to those of the object under study to highlight particular characteristics and phenomena (e.g. billard balls to introduce the concepts of momentum and kinetics of atomic particles).
- arbitrary - graphics that do resemble the concepts in question but reveal information through their spatial characteristics and the relationships between different elements of the graphics (e.g. charts, graphs, concept maps, outlines).
3 Visualization in education
Here is some (quick) brainstorming regarding different areas:
3.1 Organization of information spaces
Navigation of complex information spaces could be facilitated with visual navigation tools.
- An example for wiki visualization is (now disabled) Java Special:WikiViz visualization of this wiki or the light-weight SVG visualization you can see in the left menu. See our special pages. From time to time I test other applications - Daniel K. Schneider. An interesting Wikipedia visualization tool is wikimindmap (now open source, needs php 5.2 with curl).
- Glossary visualizations, like the ones made in the MACE project.
3.2 Concept organization
3.3 Organization of facts and concepts
3.4 Social maps
(To display social webs and show what people do)
3.5 Data visualization
To display complex (subject) data, i.e. students use a real tool to analyze various sorts of data.
E.g. to study the history of Wikipedia pages (which people contribute and how), once could use editing history of Wikipedia pages (Viégas et al., 2004).
3.6 Discussion organization
- To organize & moderate group or class discussion (e.g.     ) writable tables or other devices
Learners, can either use or build visualizations (or both of course). We shall put some emphasis on building of course ...
(to complete some day)
4.1 Software for drawing graphics
- Various concept maps (e.g. mind maps)
- Topic maps
- Various UML tools
- Tree maps and pyramid maps
- Fractal maps
- Dynamic diagrams (e.g. )
- Flow charting programs
- Ngram Viewer (search google books)
- Venn diagrams
- Tree diagrams
- Network trees
- Fishbone maps
- Spider webs
4.2 Representation languages
4.3 Viewers for formal languages
The principle is that such software can render graphs using some kind of formal representation language.
There are others ...
(really not complete, includes both )
- Graphviz (a very popular and free visualization program for which many add-ons exist, e.g. viewers)
- Treemaps for space-constrained visualization of hierarchies. by Ben Shneiderman et al. (various software, some free)
- Tulip, created by David AUBER, is a contribution of the area of information visualization, “InfoViz”. Even if the Tulip framework allows the visualization, the drawing and the edition of small graphs, all the parts of the framework have been built in order to be able to visualize graphs having more than 1.000.000 elements

- Google fusion tables - import data (csv, txt) and visualize data in basic charts but also create maps using location data.
4.5 Programming languages
- Processing is a popular open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool.
In addition to special purpose languages like "processing", any programming language with sufficient graphics can do, e.g.
4.6 Libraries for programmers
- D3.js at GiHub
- Flare is an ActionScript 3 library (really good). “Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel.”, retrieved 16:57, 19 March 2009 (UTC)
- jQT, a Zepto/jQuery plugin for mobile web development on the iPhone, Android, iPod Touch, and other forward-thinking devices.
