The main benefit of data visualization in business intelligence is its ability to present complex data in an easily digestible format, enabling quicker and more informed decision-making. By transforming raw data into visual formats such as charts, graphs, and dashboards, organizations can more effectively identify trends, patterns, and anomalies. This enhances understanding among stakeholders, allowing them to grasp critical insights at a glance. Data visualization tools facilitate communication of findings, making it easier to share information across teams and support strategic planning.
