yEd 3.15 发布了，yEd是一个画流程图的工具,不是开源软件，但是可以让你摆脱 Microsoft Office Visio ,也有linux下的版本，整个程序是java开发的，确实比较强大。
更新：
New Features
The Circular and Radial layout algorithm as well as Balloon and all Directed Tree layout algorithms support a new edge routing style where edge paths are bundled to prevent visual clutter.
Bugfixes
Disabled menu interaction on Mac OS X during layout runs to prevent accidental graph structure modifications.
Many bugfixes, great and small.
