Cardinalities on Lucidchart ERDs
How do I add cardinalities to my ERD in Lucidchart? Currently the lines are just straight and I need to show cardinality.

To connect your ERD shapes and show cardinality click on the arrow and look to the top of the editor. You will be able to adjust the arrow heads in this menu. Let me know if this works for you!
