What is the benefit of applying a context filter?

The benefit of applying a context filter lies in its ability to limit the data scope for other filters. When a context filter is set in Tableau, it creates a context in which all other filters are applied. This means that only the data that meets the criteria of the context filter will be considered when other filters are applied, leading to a more efficient filtering process.

By defining a specific subset of data as the context, you improve performance when applying additional filters by allowing Tableau to focus on a smaller dataset. This can be particularly beneficial when dealing with large datasets, as it reduces the amount of data Tableau needs to process for subsequent filters.

In contrast, removing all filters from the dataset would not provide any advantages in filtering efficiency or scope. Enhancing the visual appeal of dashboards pertains more to design elements than to the functional benefits of filters. Likewise, simplifying the data model typically involves structural changes rather than the application of context filters, which focus specifically on data processing and analysis.
