Which benefit is NOT typically associated with data visualization dashboards?

Data visualization dashboards are primarily designed to present data in a user-friendly format, making complex information easier to digest and interpret. One of the key aspects of these dashboards is to provide quick insights and help users identify trends, patterns, and anomalies in the data.

When considering the benefits typically associated with dashboards, options such as real-time performance tracking, accessibility to non-technical users, and engagement through graphical representation all highlight the strengths of dashboards in enhancing understanding and interaction with data.

In-depth data storage, however, is not a function or benefit of a data visualization dashboard. Dashboards serve as a visualization tool rather than a storage solution. Their purpose is to showcase processed data and provide a high-level overview, rather than to store large volumes of data or offer detailed data management capabilities. Therefore, option C is the correct choice, as it does not align with the primary functions of data visualization dashboards.
