Treemaps for space-constrained visualization of hierarchies

Treemaps for space-constrained visualization of hierarchies

Tree structured node-link diagrams grew too large to be useful, so I explored ways to show a tree in a space-constrained layout. My initial design simply nested the rectangles, but a more comprehensible design used a border to show the nesting. My excitement about treemaps was great and like many innovators I thought millions of users would be using this tool within a few years. Related:  Data Visualising

Concept map Diagram showing relationships among concepts A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts.[1] Concept maps may be used by instructional designers, engineers, technical writers, and others to organize and structure knowledge. Differences from other visualizations [edit] Novak's work is based on the cognitive theories of David Ausubel, who stressed the importance of prior knowledge in being able to learn (or assimilate) new concepts: "The most important single factor influencing learning is what the learner already knows. Concept maps are used to stimulate the generation of ideas, and are believed to aid creativity.[4] Concept mapping is also sometimes used for brain-storming. Formalized concept maps are used in software design, where a common usage is Unified Modeling Language diagramming amongst similar conventions and development methodologies. Concept maps are widely used in education and business.

Vintage data visualization: 35 examples from before the Digital Era This is a guest post by Tiago Veloso, the founder of Visual Loop, a collaborative digital environment for everything related to information design and data visualization. He lives in Brazil, and you can connect with him online on Twitter and LinkedIn. If you follow us regularly on Visual Loop, you’ve probably noticed we like to featured not only modern interactive visualizations and infographics, but also examples from the past, from the time when there were no computer softwares to help analyzing and designing and no Internet to access and share data. Graphics, charts, diagrams and visual data representations have been published on books, newspapers and magazines since they exist, not to mention old maps and scientific illustrations, and despite the lack of tools such as the ones we have at our disposal nowadays, they are as inspiring and important as the best contemporary visualizations.

The Creators of 30 Programming Languages: pages, biographies, blogs, interviews Behind any programming language there is a creator or sometimes a small team. Each language has a story and a philosophy and each creator had a motivation, a problem to solve. Programming languages influence and sometimes determine the way programmers solve problems and the way problems can be solved. I think it is very useful for every programmer to understand the history of programming languages and also to understand the reasoning and the way of thinking of the programming language designers; for the programming languages you love but, even more, for those you don’t like or understand. I compiled here a list of languages with their creators and some links to information about them. Most of the interviews are extremely interesting.

The Consumer-Centric Knowledge Web - A Vision of Consumer Applic By Jack Krupansky May 4, 2006 (previous: March 20, 2006 - latest ) Jump directly to PowerPoint presentation The Consumer-Centric Knowledge Web (CCKW) is a research proposal for a new knowledge-based computing infrastructure (global knowledge web platform) which will be much better-suited for consumer applications by enabling computer applications to finally understand what consumers really want. Table of Contents Introduction Software agent technology has been an active field of research for more than a decade. Please note that the intention of this vision of software agent technology is not to turn the computer into a human-like robot, but simply to enable the computer as a competent assistant in the lives of consumers. The focus of this vision is not to preview the totality of consumer applications that could be constructed, but to establish a base vision upon which consumer applications can then be envisioned .
