The New Diagram Wizard feature of WizFlow makes it easy to select from a range of color schemes and diagram sizes without the need to create a custom diagram template. It also provides a simple mechanism to change a diagrams font and text size throughout the entire diagram if needed. Use of the wizard is optional and not all diagram templates support color schemes and preset sizes. You will not find any other Flow Diagram Drawing Software with the amount of features that Pacestar WizFlow Flowcharter offers for the price. WizFlow is suitable for computers with Windows 98, Windows 2000, XP, Vista or later. WizFlow is shareware and you can download a demo from the company site to be sure the product will work on your system as well as to "get a feel" for the program and see if it will fit your needs.
