Thanks Oscar.  Your presentation is much nicer than mine.

re: 	* Matrices, parallel co-ordinates
	* Timeline and topology plots, map and landscape views

A problem for visualizations (and a huge concern of mine) is that the underlying physics of the visualization be a Socio-Technical System.  That means that physical constants remain constant under iteration by degrees (0-90) and radians (0-PI/2) in a parallel coordinate system.  Economists and for-profit businesses regularly get this wrong, because the apparent result is mighty attractive, "new and improved", "shows growth" and so forth, with some unwitting validation from Contract Law*.  Governments should not work this way - the apparent variability is 100% due to "hidden fees" (truncation on a chaotic boundary).  For example (#2), sunset and sunrise calculations are "centered" on mid-summer.  Solar Noon wanders around Local Noon according to The Equation of Time, but never more than about half an hour of a clock noon - the center of lunch hour - or Siesta.  Siesta caused many Work-Life Balance problems on the real boundary with Family Time
 around sunrise and sunset. The logical mistake was that a watch was registering the true constant labelled "noon" and the sun was being somehow disorderly - a "Watch Ethic" disguised as a "Work Ethic", it only worked on the Mid-Summer's Day.

Thanks for the confusing explanation, Gannon.  

Socio-Technical Systems fix this, the math is fairly straight forward.
If someone at KIT or FI.UPM.ES would like to help me improve the teach-ability please contact me off line.


* Example #1: A One Year Contract = 365.242196 Day Contract according to Astronomers (Kepler) and a 365.25 Day Contract according to Bankers and a 365 Day Contract according to the Payroll Department.  It's a "tri-label" not a three (tri)-nomial.

Hi Maria,

If you are interested in covering map-based visualizations, you may want to add Map4RDF (http://oegdev.dia.fi.upm.es/map4rdf/)

Dear all,

we are trying to compile a survey of topics and tools for visualizing Linked Data. This is part of the contributions of the European project EUCLID (http://www.euclid-project.eu/), which aims to provide an educational curriculum for Linked Data practitioners. So far we have created training materials on introducing the Linked Data principles and application scenarios [1], and on querying Linked Data [2]. Currently we are working on covering visualization. If you are a developer or a user of methods or tools, which are relevant and we have missed, please let us know (direct reply to the email or euclid-project@sti2.org and on Twitter https://twitter.com/euclid_project).

All training materials produced by EUCLID are freely available [3] (Attribution) and can be reused for trainings and educational activities. 

	*  Linked Data Visualization
	* Visualisation Techniques
	* Visualizing the Linked Data Cloud
	* Requirement for Visualisation Tools
	* Visualizing Different Data Dimensions
