Diagrams frequently asked questions.
Miscellaneous
Can I render a diagram to the screen and then know which part of the diagram a user has clicked on?
Yes. See the user manual section on using queries.
When I try to compile, the linking phase hangs eating CPU and never finishes
It seems this can be caused on OS X by a mixture of 32- and 64-bit libraries. For example see this bug report. Ensure that your GHC and your gtk libraries are either both 32-bit or both 64-bit.
Error messages

This is due to a bug in GHC. As a workaround, you can simply add the import
import Diagrams.Core.Points
