There’s a nice list of data visualization tools available on netmagazine. I think it would be really interesting to experiment with a few of these in the context of the redevelopment of the OLnet Evidence Hub in the OER Hub project.
- Modest Maps could be used instead of Google Maps to provide geolocation for organisations, input from TrackOER, etc.
- Polymaps looks like it could do the same job but maybe while looking a bit nicer…
- OpenLayers may have the best functionality while being a bit trickier to use
- Google Chart API would allow us to create a range of dynamic visualizations
- D3 offers similar functionality for a wider range of outputs: Voronoi diagrams, tree maps, circular clusters and word clouds
- Crossfilter and Tangle allow you to create interactive visualizations and documents which can be manipulated in real time… I think these could be a really useful way to present information
- Processing also offers interactivity, though it’s not clear to me how easy it would be to integrate these kinds of elements
- Apparently R is good, but with a steep learning curve
- Gephi is a good choice for a graph-based visualiser and data explorer
There’s a Tumblr page at http://vizualize.tumblr.com/ which looks worth checking out in more detail.
