Cheap Data Visualization

There are lot of possibilities here.  This slideshow outlines them.  I also see  that Tableau 8 is out today, plan to look at that excellent package for interactive data visualization.    They have a free form called Tableau Public that you can use for personal visualization needs without an enterprise budget.  Lots of other options, its an area that has received much attention recently.  I will look at a few and come back with some recommendations.  In particular I am further interested in solutions that will work well on mobile tablets. Let me know if you have recos beyond the side show.
