We are examining more interfaces for map animations and visualizations. It is a complex interplay of legibility and intuitiveness versus graphic design and screen real estate. It is paramount that the user can quickly and correctly figure out what they can do (don't assume your audience is all that computer savvy). But do think creatively with regard to your topic and design theme. This website called Pattern Browser is an attempt to categorize a multitude of online visualizations with reference to the interface. It has a strong emphasis on geographic data and the needs of spatial info.
The other main component this week is learning a new approach for visualizing complex data -- the "faux-GIS." This is a layering technique where a static map image is overlaid with a variety of pre-made maps of the same geographic location. The user is given the ability to control the viewing of the maps (which layers to see and how many to overlap), but the maps themselves are all pre-made (dynamic maps are very doable and quite compelling...but we're not up to that level yet). The issues with this visualization approach stems with the concentration of data symbols. It is challenging to produce multiple maps that retain legibility when layered together (as if a stack of overhead transparencies). Simplicity is key. It is possible to retain detailed info, but you have to think carefully.
Below are some examples of this layering approach:
Here is one on Sudan by the Washington Post which is very nice.
And Iraq animation has layers in addition to temporal content (could inspire a final project)
2008 Campaign Finance Tracker has a variety of ways to search through the data.
And this is just an interesting way to search for news geographically
