Comparison

Netgraf vs Gephi

Gephi is free, open-source desktop software for analysing and visualising large networks, from ten to millions of nodes. Netgraf is a free browser tool for drawing, explaining and sharing maps of people. They work well together: draw and share in Netgraf, export GraphML, and continue in Gephi when the network outgrows it.

When to choose Gephi

  • Your network has thousands of nodes or more.
  • You need layout algorithms, statistics or plugins beyond the core measures.
  • You are producing publication graphics or doing research that has to be reproduced in a standard tool.

When to choose Netgraf

  • You are drawing a network by hand from what you know, not loading a dataset.
  • You need people with names, roles, photos and dated, sourced ties rather than anonymous nodes.
  • You want to send a map to someone who will never install software, and have them understand it.

Moving between them is lossless for the network itself. Netgraf imports GEXF, Gephi's own format, and exports GraphML, which Gephi opens with every measure attached as a column.

Questions

Is there an online version of Gephi?
Yes. Gephi Lite is a browser version of Gephi aimed at lighter analysis. Netgraf is another browser option, built around drawing and sharing maps of people rather than analysing imported datasets.
Can I open a Netgraf map in Gephi?
Yes. Export the map as GraphML and open it in Gephi. People, ties, direction and the network measures Netgraf computed all come across as attributes.
