To get the most out of this book

This book will make a great choice for collaborative data analysis work within a cross-functional team of data analysts, business professionals, and software engineers.

Many common analytical questions on data can be addressed using the charts, which are easy to use.

A working knowledge of Python will be an advantage but is not necessary to understand this book.
