First and foremost, I would like to thank my mom, Lakshmi, for her support throughout my career and in writing this book. She has been my inspiration and motivation for continuing to improve my knowledge and helping me move ahead in my career. She is my strongest supporter, and I dedicate this book to her. I also thank my family and friends for their encouragement, without which it would not be possible to write this book.

I would like to thank my acquisition editor, Aman Singh, and content development editor, Mayur Pawanikar, who chose me to write this book and encouraged me constantly throughout the period of writing with their invaluable feedback and input.

I wish to thank my fiancée, Dorothy, for her constant love and support, especially during the difficult time in balancing family, work, and life. On behalf of the authors, I would like to thank the wonderful team at Packt Publishing—Mayur, Tushar, Vikrant, Vivek, and the whole editorial team who helped in the creation of this book. Thanks to Tushar's introduction, the authors feel greatly honored to take part in this amazing project. Special thanks and much appreciation to Mayur for guiding the production of this book from the ground up. The authors truly appreciate the comprehensive reviews from Nikhil Borkar. We cannot be thankful enough to the entire Matplotlib and Python community for their hard work in creating open and incredibly useful tools. Last but not least, I would like to express my sincere gratitude to Prof. Ting-Fung Chan, my parents, friends, and colleagues for their guidance in my life and work.
