新手问题 这个挺赞 Graphic overview of Library 怎么实现的？
在 Gem: Spreadsheet 的 README.md 里看到一个Graphic overview of Library, 很赞，列出了 gem 中 Class 及继承关系。
请教这是用什么工具做的？有没有更好的，或者相关的工具？
谢谢！
#1 楼 @mimosa RailRoad has been tested with Ruby 1.8.5 and Rails 1.1.6 to 1.2.3 applications. There is no additional requirements (nevertheless, all your Rails application requirements must be installed).
Ruby on Rails 3/4 model and controller UML class diagram generator. Originally based on the 'railroad' plugin and contributions of many others. (sudo port install graphviz before use!)
