This is a list of free software tools that can be used for the visualization of datasets such as those produced by the ENUMERATE surveys.
While been free, these tools still require a varying effort of development to be proficiently employed. If you build some original data view from the ENUMERATE datasets using these or any other tool, please tell us, we will link to your visualization or will try to embed it in this site.
This is a really powerful library which can be used to create all kind of compelling data graphs, from the simplest to the really advanced. Unfortunately, it is no longer under active development, having been superseded by D3.js (see next paragraph).
As stated, D3 is not only a data visualization library, but a whole document manipulation framework, with data visualization as a subset of its functionality. In that way is much more powerful than Protovis but somehow more complex.
- Mondrian (http://www.theusrus.de/Mondrian/) - A general purpose statistical data-visualization. It features outstanding interactive visualization techniques for data of almost any kind, with particular strengths for working with Categorical Data, Geographical Data and Large Data. Published under a GPL license, Mondrian is written in Java, and requires some effort to be integrated in web sites.
- VisIt (https://wci.llnl.gov/codes/visit/about.html) - VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes.
Available under a BSD license, it has C++, Java and Python interfaces. It is best suited for the visualization of engineering and scientific datasets, and a bit of overshoot for small statistical datasets.
- InetSoft's Visualize Free (http://visualizefree.com/) - A commercial product with a free visual analysis tool version. Flash and Java based.
This is a relatively simple to use service, somehow exposed to the usual Google API weaknesses: it can be changed or deprecated, or its licensed changed with little warning. Oriented to programmers.
- Google Fusion Tables (http://support.google.com/fusiontables/answer/2571232) - An experimental tool for uploading datasets to Google Docs, sharing and visualizing them. Oriented to end users, it seems promising but documentations is somewhat lacking.
