Graph library in Lua

Is there a Lua library (or 开发者_C百科with Lua bindings) to build graphs (directed/undirected), with traversal algorithms, connectivity tests, and other basic graph operations?

The LuaGRAPH library is a Lua binding to GraphViz that might suit your needs.

Features

• Define graphs using Lua syntax elements (tables, functions)
• Layout and render graphs
• Iterators for subgraphs, nodes and edges
• Set and get for all graphviz attributes for graphs, nodes and edges
• Set and get user defined properties (even methods) to any graph object
