Annotated VisiRule Charts

Here are various charts annotated with comments as PDFs. Each chart intends to expose some aspect of VisiRule which is explained in the accompanying PDF document. You can request any of the charts on this page if you want.

Domain knowledge is well suited to VisiRule's way of graphical modelling and self-publishing. VisiRule is designed to be used by business experts and knowledge holders, NOT programmers. Authors are lawyers, accountants, tax experts, product engineers. VisiRule enables knowledge specialists to author and publish charts themselves in the form of interactive expert systems. No programming skills required. The need to involve programmers often leads to communication problems and takes away control from domain experts.

Drawing Logic




The basic goal of VisiRule is to enable you can do simple things very easily with basic drawings. Then, by using some of the more advanced features, you can manipulate text, numbers and logic alongside your drawings. 


VisiRule supports different question types, which use logical expressions and mathematical formulae to process the answers.

The annotated charts on this page help show how to exploit various of these aspects within your charts.
