Scientific Visualization Studio (NASA)
From the website:
The mission of the Scientific Visualization Studio is to facilitate scientific inquiry and outreach within NASA programs through visualization. To that end, the SVS works closely with scientists in the creation of visualization products, systems, and processes in order to promote a greater understanding of Earth and Space Science research activities at Goddard Space Flight Center and within the NASA research community.
All the visualizations created by the SVS (currently totalling over 4,200) are accessible to you through this Web site. More recent animations are provided as MPEG-4s, MPEG-2s, and MPEG-1s. Some animations are available in high definition as well as NTSC format. Where possible, the original digital images used to make these animations have been made accessible. Lastly, high and low resolution stills, created from the visualizations, are included, with previews for selective downloading.
A visualization of data site that may have visualizations that work with your topic maps as content and/or give you creative ideas for visualizing data reported by your topic maps.
For example, consider: Five-Year Average Global Temperature Anomalies from 1880 to 2011. Easier than reporting all the underlying data. This may work for some subjects and less well for others.
