Extending Power BI with Python and R

By: Luca Zavarella

Overview of this book

Python and R allow you to extend Power BI capabilities to simplify ingestion and transformation activities, enhance dashboards, and highlight insights. With this book, you'll be able to make your artifacts far more interesting and rich in insights using analytical languages. You'll start by learning how to configure your Power BI environment to use your Python and R scripts. The book then explores data ingestion and data transformation extensions, and advances to focus on data augmentation and data visualization. You'll understand how to import data from external sources and transform them using complex algorithms. The book helps you implement personal data de-identification methods such as pseudonymization, anonymization, and masking in Power BI. You'll be able to call external APIs to enrich your data much more quickly using Python programming and R programming. Later, you'll learn advanced Python and R techniques to perform in-depth analysis and extract valuable information using statistics and machine learning. You'll also understand the main statistical features of datasets by plotting multiple visual graphs in the process of creating a machine learning model. By the end of this book, you’ll be able to enrich your Power BI data models and visualizations using complex algorithms in Python and R.

Chapter 16: Interactive R Custom Visuals

In Chapter 15, Advanced Visualizations, you saw that it is possible to make very complex graphs thanks to the flexibility introduced by ggplot. Sometimes, however, you have the feeling that you can't take full advantage of the information shown in the graph because of a lack of interactivity, such as tooltips. In this chapter, you'll learn how to introduce interactivity into custom graphics created using R and by directly using HTML widgets. Here are the topics we will cover:

  • Why interactive R custom visuals?
  • Adding a dash of interactivity with Plotly
  • Exploiting the interactivity provided by HTML widgets
  • Packaging everything into a Power BI custom visual
  • Importing the custom visual package in Power BI
