A data dashboard is a visual tool that collects, organizes, and displays key data points in real time. It presents complex information through charts, graphs, and tables, making it easier for users to monitor, analyze, and understand important metrics at a glance. Data dashboards are commonly used in business, marketing, and cybersecurity to track performance, identify trends, and support decision-making. They help users quickly spot issues or opportunities by presenting up-to-date data in an accessible, interactive format.
