That flowchart you made in Gliffy Online is getting too big. Plus, you want to give an nice flowing presentation of it to your boss so you can get that shiny new Bugatti Veyron as a bonus. This is where embedding links in your diagram and public diagrams comes in.
In your Gliffy diagram, rather than place all sections of your diagram on one page, create a new diagram for each sub flow or sub-section of your diagram. In the main diagram use a shape link or text link to show the link to the sub flow. Then, in each Sub-flow diagram, include a hyperlink and include text such as, 'back to Main Flow'.
Now, go ahead and publish each diagram (Share->Publish->Public). Record the public URL’s to each sub flow diagram and the Main Diagram.
Next, in the main flow diagram, for each sub-process you want to connect, highlight the text or shape that is a link to that sub flow diagram. Click the 'link' button and enter the public URL.
Finally, in each sub-flow diagram highlight the text or shape that is a link to the main flow diagram. Click the 'link' button and enter the public URL for the main flow diagram.
You now have a way of easily presenting a large process flow, with clickable links to each sub flow.
