OmniGraffle is a program designed primarily to make graphs and charts quickly and easily as possible.
The program includes lots of bookstores to find the style that best suits what you want to do, whether business graphics, school work …
In addition to this OmniGraffle allows signs, family trees, different types of structuring information according to what is intended what we are doing (a science project, a presentation of the balance sheet of a company at the end of the year …).
Although OmniGraffle is aimed at a professional level using the program it is made easy through a friendly interface.
OmniGraffle lets you export graphic files to different formats in order to facilitate integration into Web.
