At this point students have already created/worked with a couple models and created basic graphs to visualize them.

Visualization is a graphical representation of data for the purpose of allowing humans to understand aspects of the data. Just having data isn't enough. We have to understand what the data means. Without visualization our models are a lot less useful because we have no other way to understand what's happening in our models short of complicated numerical analysis. It also gives us a way to share useful information by compacting it into a powerful visualization that communicates all the information quickly.

			==== Issues of Visualization ====

			* Objective. There is always a goal or objective when visualizing by which one can judge effectiveness. In this class I don't think things like marketing should be mentioned but certainly the difference between using visualization to explore data and to explain data to others.
			* Data Selection. When given a set of data, often one wants to single in on a subset of that data to look at.
			* Psychology. Visualization is fundamentally about how humans perceive visual information so you have to think about the ways in which you want to take advantage of human psychology.
			* Systemization. While elaborate visualizations like the Napoleon one are very compelling, in Computer Science we are often more interested in visualizations that can be systematically generated.

			==== Types of Visualizations ====

	* Issues of visualization		We are all familiar with common visualizations like graphs and tables, but now with computers we can create much more advanced visualizations that give us more information.

	* Go through a couple of examples of creating visualizations referring back to Tufte's list and the issues.
	* Types of Visualizations (A sampling)
	** Tables
	** Graphs
	** Charts
	** Sparklines
	** Time Series
	** Data maps and mashups

			* 3d physical models that give us interactive 3d structures that are potentially updated by new information in real time to allow us to give us a lot of information but also allow us to choose what aspect of the data to focus on. For example visualizing a model of a car crashing into something can give people a chance to actually see whats happening to all the different parts of the car from potentially a number of different angles.

			* Animated models allow use to use time as a dimension so we can put together more information. The animation could either represent how the model changes over time, or represent some other aspect of the model. The Gapminder visualization uses time to allow us to look at the different aspects of the world at each point in time so that not only can we see how the different countries interact but how those interactions have changed throughout the years.

	~~=== Examples ===~~		* Data maps and mashups are another new type of visualization the comes from now having detailed maps of the world with respect to a variety of different information sources. We have everything from satellite photos to road maps to weather data to census data. Using all these different sources combined on a single map we can see easily see how the different aspects correlate. In the lab students will be collecting temperature data and mashing it with satellite images.
	~~Show some examples and ask what their pros~~ and ~~cons~~ are ~~and what insights they allow. Go through Tufte's list and identify which rules~~ the ~~visualizations follow~~.

			* It is impossible to create 3 axis graphs in open office. Perhaps add more detail on how to create a working bar graph in OO.
			* GPS is mighty inaccurate. I am working on trying to get the differential working but perhaps it would be advantageous to have points taken from multiple areas.
			* We need more thermometers.
			* I didn't do the google docs part as I had no collaborators.
			* The instructions need to be more detailed on how to add points to a map on google maps
