Welcome

Data Visualization Using Power BI guides you through the complete analytics workflow, from connecting to data all the way to sharing insights across your organization. You will learn to bring in data from Excel, CSV files, and SQL databases, clean and reshape it in Power Query Editor, and build star schema models where fact and dimension tables are connected through well-defined relationships.

From there, the book moves into report building, covering core visualizations, slicers, filters, and DAX (Data Analysis Expressions) measures that go beyond what drag-and-drop alone can produce. Advanced chapters extend this further with time intelligence calculations, Key Influencers, and paginated reports that address real analytical questions rather than surface-level summaries. The final part introduces the Power BI Service, where reports are published, datasets refresh on a schedule, and access is managed through workspace roles, so the right people always see the right data. Whether you are building your first dashboard or scaling analytics across a team, this book gives you the practical skills to work with data confidently at every stage.
