这三章让你开始进入可视化世界，但要学的东西还有很多。学习更多知识的最佳途径是 ggplot2 一书：ggplot2：Elegant Graphics for Data Analysis》（施普林格出版社）。这本书更深入地介绍了基础理论，并提供了更多如何将各个部分结合起来解决实际问题的示例。另一个很好的资源是ggplot2 扩展库。该网站列出了许多用新的地理位置和尺度扩展 ggplot2 的软件包。如果你想用 ggplot2 做一些看起来很难的事情，这是一个很好的起点。

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
