What is one advantage of using layout templates in dashboard development?

Using layout templates in dashboard development provides the significant advantage of offering a consistent end user experience. This consistency is crucial for users, as it allows them to quickly understand and navigate the dashboard without needing to adapt to different layouts or designs each time they access a new report or dashboard.

By using predefined templates, developers can ensure that similar data types and visuals are presented in the same manner across various dashboards. This not only enhances usability but also strengthens brand identity and familiarity for users, making them more comfortable and productive when interacting with the analytics.

In contrast, the other options indicate disadvantages of layout templates. Customization may be significantly reduced, and while templates do provide some degree of design flexibility, they do not offer unlimited design variations, which can lead to commonality rather than uniqueness. Moreover, the use of templates is intended to simplify, rather than complicate, the dashboard-building process.
