ubuntu16.04下面使用graphviz

不推荐下载deb，因为找到的deb貌似较多是给debian用的，很多依赖包都是debian的源里面的就不太好处理了。

还是直接apt-get install graphviz比较好。自己使用的源列表是：

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted


# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://cn.archive.ubuntu.com/ubuntu/ xenial main restricted
# deb-src http://cn.archive.ubuntu.com/ubuntu/ xenial main restricted


## Major bug fix updates produced after the final release of the
## distribution.
