Hi Samuel,

I do support your last idea to switch only lstopo to the physical numbering.

I would also like to ask you to consider adding the Title to the graphical
output so that users can distinguish easily if the graphics was created with
--physical or --logical numbering.

Adding single line to the top of graphics which says:
"This graphics is using [physical|logical] numbering. See man hwloc for

would make it clear.
