What advantage does Canvas offer compared to Graph regarding card visibility?

Canvas offers a significant advantage in that it allows users to hide cards from view. This feature enhances the user experience by providing a cleaner interface and enabling users to focus on specific data without distractions. By hiding cards, users can tailor their workspace to highlight only the information that is relevant at any given time, which can improve productivity and analysis.

In contrast, the other options do not accurately represent the advantages associated with Canvas. For instance, while some functionalities relate to card management, such as deleting or merging, these do not specifically address card visibility, which is the core focus of the question. The ability to resize cards is unique to Graph and does not contribute to the visibility management provided by Canvas. Thus, the capability to hide cards in Canvas is a distinct feature that sets it apart in terms of enhancing user control over the information displayed.
