Hi David, The file graphview.svg contains a svg-drawing: a circled letter 'a' pointing to a circled letter ‚b' which I added to my email, but the png-image was removed from my email.
I assume that this svg-file is the expected answer. So, I assume that dot is working as expected and without errors. To answer your question completely: The command ldd under Linux is not available on a Mac, but 'otool -L‘ gives similar answers: /usr/local/bin/dot: /usr/local/Cellar/graphviz/2.40.1_1/lib/libgvc.6.dylib (compatibility version 7.0.0, current version 7.0.0) /usr/local/opt/libtool/lib/libltdl.7.dylib (compatibility version 11.0.0, current version 11.1.0) /usr/local/Cellar/graphviz/2.40.1_1/lib/libxdot.4.dylib (compatibility version 5.0.0, current version 5.0.0) /usr/local/Cellar/graphviz/2.40.1_1/lib/libcgraph.6.dylib (compatibility version 7.0.0, current version 7.0.0) /usr/local/Cellar/graphviz/2.40.1_1/lib/libpathplan.4.dylib (compatibility version 5.0.0, current version 5.0.0) /usr/lib/libexpat.1.dylib (compatibility version 7.0.0, current version 8.0.0) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.11) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.200.5) /usr/local/Cellar/graphviz/2.40.1_1/lib/libcdt.5.dylib (compatibility version 6.0.0, current version 6.0.0) Regards, Ulrich > Am 04.07.2019 um 14:36 schrieb David Mitchell <davidmitch...@att.net>: > > Your message seems to be truncated.
