Which diagram link allows you to share without adding collaborators?

The correct answer is Public. A Public diagram link facilitates sharing the diagram with anyone who has access to the link, without the need to add specific collaborators. This means that there are no restrictions on who can view the content, making it easy for broader audiences to access the information without requiring them to be invited or added as collaborators.

In contrast, a Private link typically necessitates that users be specifically invited in order to view or interact with the diagram. This option is more restrictive and is suitable when control over who can access the information is necessary. Similarly, a Restricted link implies that there are limitations on who can view the content, often requiring additional permissions or approvals, which again is contrary to the open access provided by a Public link. The Collaborative link, while allowing for shared access, is designed for users who need to interact with the diagram, rather than simply view it. This option is more focused on collaboration and teamwork rather than straightforward sharing.

Thus, the Public link stands out as the best choice for sharing a diagram broadly without necessitating collaboration or specific user access permissions.
