I really did create that in inkscape. If I had created it in
graphviz:
$ dot -v
dot - graphviz version 2.43.0 (0)
Huh. What I really did was to grab a random .svg, pull that into
inkscape, and edit it. So let's see what we have:
$ find . -name '*.svg' -exec grep -l 'Generated by graphviz version' {} \;
./memorder/fr.svg
./memorder/fr-hopes.svg
./memorder/rf.svg
./memorder/rf-hopes.svg
./memorder/co.svg
./memorder/co-hopes.svg
./memorder/co_backup.svg
./memorder/co-hopes_backup.svg
And memorder/co.svg was created in 2017, which might be consistent
with a 2014 graphviz. Except that why would I use graphviz to create
something like that? I most definitely recall manually adjusting to
create those colored polygons, and that would not have been the experience
with graphviz.
The original was in LibreOffice. Maybe I somehow used graphviz to convert
from LibreOffice format to .svg? Maybe LibreOffice uses graphviz to
do exports? (But lately I just use control-C/control-V to copy/paste
from LibreOffice to Inkscape, though not always with great results.)

On the other hand, I definitely did something strange to create those
files. Because I have to hand-edit the .svg file to change font sizes.
If they cause you much more trouble, please let me know. It might be
best for me to just re-create them from scratch.
Thanx, Paul
