The Microsoft Office for Mac team has released a new video highlighting Sparklines and photo editing in the forthcoming release. Office for Mac 2011 is due in October and the Office for Mac Blog is attempting to wet customer's appetites with previews of new features. Sparklines, which debuted in Excel 2010 for Windows, arrive on the Mac side in Excel 2011 for Mac. The feature provides numerical graphs that quickly show changes in data over time. They can be generated in cells near corresponding raw data to give fast visual illustrations for numeric data.
