What core technologies are used to build Power BI dashboards?

Power BI dashboards leverage several technologies, including DAX (Data Analysis Expressions) for complex calculations, Power Query for data transformation, and SQL for database connectivity. Additionally, Power BI integrates with cloud services like Azure and uses REST APIs for custom solutions. Its visualization engine relies on HTML5, JavaScript, and CSS to create responsive, interactive dashboards. Together, these technologies enable developers to design efficient, real-time reporting systems that display insights from multiple data sources.
