Libraries for visualizing graphs in real-time using C++

Are there any good C++ libraries that can be used to visualize a graph of objects that have been instantiated and have random connections to each other? I would also need it to be able to be updated in real-time 开发者_运维技巧so that the graph was constantly updated.

If you use the Boost Graph Library then it supports the graphviz dot language. Otherwise it shouldn't be hard to write the code on your own.
