Here is the agenda of the presentation. I will talk about the role of flowchart diagrams in my experience and give an example of a large scale project which looks quite convincing to me. Then we will discuss the graphics primitives which could be used to represent the code on a diagram. A tool which implements this feature and proves the feasibility of it will be presented after that. The following discussion will be about how the flowchart generation is implemented. And the final topic will be about the other functionality which could be relatively easy added to graphics but could not be added to text.
