I want to be able to build a number of flowcharts in wordpress pages looking similar to the attached flowchart. Thats easy with a graphics program, BUT want I want is the words in the flowchart to be clickable. Anyone have any idea how to do this or point me in the right direction to work it out? Thanks.
Seems to me that what you are looking for is called "image mapping". Its been quite some time since I used it but I would imagine TinyMCE still has a plugin that works with it in the advanced option.
