free visual editor for graph (dot) files [closed]
To save time those eager to try existing programs handling DOT graphs:
- dotty can display DOT graphs and with little luck you can move its nodes with a mouse, nothing more, and you can easily segfault as a bonus (I tried latest stable graphviz)
- lefty is only a special-purpose language interpreter used by dotty, nothing to look at
- KGraphEditor is an empty wishful project (a QT window and a few buttons)
- gvedit is not really a graph editor: it provides a simple text editor and you hit F5 to run a layout tool and open a picture; you can actually get more functionality from configuring your own favourite text editor
- grappa is an abandoned java applet, which I failed to run
- interestingly, dia can export to DOT ("PyDia DOT Export"), but due to its buggy printing, you have to post-process the files to use them
- graphedit can read in DOT a graph and you can move its nodes around and change their colors
- Eclipse people started working on DOT support in GEF4, so it can display DOT graphs
- GraphUI has a very interesting demonstration video, but beware: although it might seem that the graph is being created by clicking and dragging, in reality all editing happens through the keyboard, using shortcuts. On the plus side, contextual instructions are always available showing which shortcuts do what.
- DotEditor claims a tree editor, modifying node attributes/color/shape with mouse.
The graph editors mentioned in other answers, yEd (a Java application) and JointJS/Rappid (a JaveScript thing) apparently have nothing to do with DOT (tried both).
I believe there exist no working DOT-handling graph editor out there at all.
