We're building an application that is like an interactive flow chart. When users are viewing the flow chart, they can interact with certain shapes:
- Link to another flow chart.
- Link to an external file
- A popup that shows more details when clicked.
The problem that I've encountered is how to properly identify that the shapes are clickable and also which action occurs when clicked.
These are our current ideas:
Flow Chart Link:
External File Link:
We also add the pointer cursor when hovering over the shape. However, I'm really having difficulty accepting these as very intuitive and clear. FWIW - each shape can also have a different geometry (rectangle, diamond and ellipse) and color.
I would also appreciate suggestions for better icons.
