From the Research Lab at Stanford University, Palladio is a web-based platform for the visualization of complex, multi-dimensional data.  They view it as the first step toward opening data visualization to any researcher by making it possible to upload data and visualize within the browser without any barriers. There is no need to create an account and they do not store the data. Several tutorials are available as well as a dataset to try out.
