Overview of this book

The latest edition of this book delves deep into advanced analytics, focusing on enhancing Python and R proficiency within Power BI. New chapters cover optimizing Python and R settings, utilizing Intel's Math Kernel Library (MKL) for performance boosts, and addressing integration challenges. Techniques for managing large datasets beyond available RAM, employing the Parquet data format, and advanced fuzzy matching algorithms are explored. Additionally, it discusses leveraging SQL Server Language Extensions to overcome traditional Python and R limitations in Power BI. It also helps in crafting sophisticated visualizations using the Grammar of Graphics in both R and Python. This Power BI book will help you master data validation with regular expressions, import data from diverse sources, and apply advanced algorithms for transformation. You'll learn how to safeguard personal data in Power BI with techniques like pseudonymization, anonymization, and data masking. You'll also get to grips with the key statistical features of datasets by plotting multiple visual graphs in the process of building a machine learning model. The book will guide you on utilizing external APIs for enrichment, enhancing I/O performance, and leveraging Python and R for analysis. You'll reinforce your learning with questions at the end of each chapter.

Choosing a circular barplot

Very often, we need to display the measures associated with different categorical entities using a bar chart (or barplot). However, when the number of entities to be represented exceeds 15 or 20, the graph begins to become unreadable, even if it is arranged vertically:

In this case, as you saw in Chapter 19, Exploratory Data Analysis, it is often a good idea to plot a maximum number of entities and then group the subsequent entities into a single category (in our case, the Others category). This preserves the readability of the graph, but loses some of the information you want to represent.

If it is absolutely necessary to display all entities with all their dimensions, we often resort to a more eye-catching organization of the space occupied by the barplot, wrapping it in a circular shape, thus obtaining a circular barplot:
