Power BI dashboards can be customized to meet the needs of different users by tailoring visualizations, filters, and layouts. For example, executives may prefer high-level summaries of KPIs, while analysts might need detailed charts with drill-down capabilities. Power BI allows the creation of role-based dashboards, where permissions determine which data is accessible to each user. Customizing visuals, such as charts, maps, and tables, based on user preferences ensures relevant insights and improves user engagement with the dashboard.
