Rexamining Excel 2013

In preparation for a conversion to a more generalized data visualization system I have been exploring Excel 2013 use for visualization.   It is commonly used in industry.   Much data is already accessible in Excel.  I am impressed by the recent changes that have been made for quick prototyping.   And the addition of Sparkline capability.  There are still issues with the intuitiveness of the interface.   More on whats new there.
