QVGE is a multiplatform graph editor written in C++/Qt.
Its main goal is to make possible visually edit two-dimensional graphs in a simple and intuitive way.

Main features of QVGE:

  • Easy creation and parameterising of small-sized till middle-sized graphs (1000+ nodes/edges)
  • Common visual properties of nodes and edges: shapes, sizes, colors, labels etc.
  • Custom (user-defined) attributes of graphs and their elements
  • Drawing of directed, undirected and mixed graphs
  • Nodes can have ports
  • Straight and polygonal edges supported
  • Dynamically maintained list of commutations between nodes
  • Search among the graph elements and their attributes
  • Auto-creation and auto-layout of graphs (via OGDF)
  • Export of graphs into PDF, SVG and various image formats (BMP, PNG, JPG, TIFF etc.)

Graph file formats supported:

  • XGR (native graph persistence format)
  • GEXF (read/write of common subset, except clusters and dynamic properties)
  • GraphML (read/write)
  • GML (read via OGDF, write via QVGE)
  • GraphViz DOT (read/write, only common subset for now)
