How to disable gojs flowchart upon loading?

I have a gojs flowchart getting loaded upon button click,
i want the flowchart to be non editable, i.e. user should not be able to edit the flowchart once it is loaded.

I tried a number of options but nothing worked for me.

Can you please help ?

What options did you try? How were they unsatisfactory?

Read http://gojs.net/latest/intro/permissions.html about your choices.

I tried disabling the div that contains the model diagram pallet.

However, the link that you referred served the purpose i was looking for.

Thanks.
