Wow. Figures contain no color.
June 20, 2019
Apologies to the author for the low-rating. After purchasing this book, I expected color, not gray-scale, used in the (many) visualizations, especially based on the content. Color is important to understanding the material.
I'm not sure if the author had a say in this, or this is O'Reilly's doing, but I would respectfully suggest that if leaving out color in the visualizations was intentional, it's not the way to go.
Based on this, I regretfully suggest that you DO NOT purchase the book. In my view, the book is significantly diminished because of this omission, and I think you'll agree, especially if you purchased at full price as I did.
Does the Kindle version have color? Not sure. I wish I could still purchase PDF's, but that was closed some time ago.
I'm starting to think this is my last O'Reilly book purchase. Perhaps the intent is to move us all to Safari subscriptions.
