Alternative of Microsoft Visio? I am looking for a good alternative of Microsoft Visio for Mac OS X.
I need an application to create a schedule of the month or something like this and then to print it.
I recommend OmniGraffle Pro (http://www.omnigroup.com/omniGraffle) from the Omni Group.  They have a standard and pro version.  You can download trial version of either the standard or pro version.
