全書從Python程式語言切入，讓不懂Python的讀者也能快速上手。之後介紹處理數值最重要的套件包括NumPy和Pandas，接下來就是Python最重要的繪圖套件，包括matplotlib、Seaborn和plotnine的圖形語法，以及資料視覺化的顏色主題運用原理。在熟悉了工具之後，就進入本書的高潮，製作各式各樣的圖表，包括直條圖系列、橫條圖系列、南丁格爾玫瑰圖、徑向柱圖等圖表。還有資料關聯式圖表，包含二維和三維散點圖、氣泡圖、等高線圖、立體曲面圖、三元相圖、二維和三維瀑布圖、相關係數熱力圖等。最後更直接畫出了「商業週刊」、「華爾街日報」、「經濟學人」等刊物中最專業的圖表，直接晉升成大師行列。

English only documentation is starting to be a major problem for the scientific python ecosystem. This book provides an introduction to the basic usage of Matplotlib, the underlying structure of the architecture, and several of the high-level libraries built on top of matplotlib. Hopefully, this book will provide the context needed for Chinese speakers to better approach and understand the canonical English documentation of the projects.

Python語言生態圈有一個很主要的問題就是只有英文參考文件。本書介紹了matplotlib套件的基本用法和底層架構，以及建構在Matplotlib套件上幾個高水準的套件(Plotnine、Seaborn和Basemap等)。希望這本書能給中文讀者提供所需的學習內容，更好地幫助讀者學習與了解這些經典的英文技術文件。

When trying to understand or communicate information one usually asks, what is the best visualization(s) I can make? If this question often comes to you and that you tend not to have an answer, then "Beautiful Visualizations with Python" is meant for you. Python is an excellent language for data analysis and visualization. Secondly, the book helps you build a practical toolbox for most visualizations that you may want to create. It strikes a delicate balance between a book that introduces and teaches and a gallery that you can always come back to for ideas. It is not one to throw away after reading. As it is titled, you will learn how to turn data in into beautiful visualizations by making the best choices at every step. Most important for me is that it covers the biggest idea in data visualization in the last 20 years, that is, "The Grammar of Graphics".
