deplacy.render(doc,BoxDrawingWidth=1,EnableCR=False,CatenaAnalysis=True,file=None) renders doc on a terminal. For old terminals, whose Box Drawing characters are "fullwidth", BoxDrawingWidth=2 nicely works. For several languages with "proportional" characters, EnableCR=True may work well. CatenaAnalysis=False disables Immediate Catena Analysis.

deplacy.serve(doc,port=5000) invokes a simple web-server to visualize doc with SVG. Try to connect http://127.0.0.1:5000 with your local browser.

deplacy.dot(doc) returns raw DOT string for graphviz.Source.
