The interwiki bot now supports creating graph views to help you resolve interwiki conflicts.
Installing pydot 
You will need pydot which is freely available here. pydot requires the free software Graphviz which is available for Windows, Linux and MacOS. You will also need pyparsing. To install pydot and pyparsing, you might need python-devel on some Linux distibutions.
Creating graphs 
After installing pydot, set interwiki_graph = True in your user-config.py. If interwiki.py encounters a conflict, it will save a graph as a PNG graphic into your interwiki-graphs directory.
Other graphics formats are supported as well. For example, you can set interwiki_graph_formats = ['svg'] in your user-config.py. This also has the advantage that the SVG format allows hyperlinks; nodes will be clickable when you use SVG, leading to the respective wiki page.
Please note that it is currently not possible to properly render certain fonts, e.g. Japanese.
