What does the term 'linked widgets' refer to in a dashboard context?

In the context of dashboards, the term 'linked widgets' specifically refers to widgets that share a common data source and can synchronize changes. This means that when data is updated in one widget, it can automatically reflect those changes in the linked widgets. This synchronization is key in ensuring that users can see related information across different parts of the dashboard without having to manually refresh or update each widget individually.

This functionality enhances the dashboard's interactivity and usability, providing a cohesive view of data where insights can be drawn through the relationships between the different visual elements. As a result, users are better equipped to analyze complex data sets and make informed decisions based on real-time information.

The other options do not accurately capture the essence of what 'linked widgets' represent. While connected external databases may be a feature of some widgets, they do not inherently imply synchronization. Widgets that display unrelated data or are simply grouped together visually do not convey any functional connection or interactivity, which is vital for the concept of 'linked widgets'.
