Is this the diagram labelled

Figure 6. Embedded-MTA Secure Power-on Initialization Flow (IPv4 eCM)?

In what format are the data specifying the components of the diagram
provided?

Despite appearances (which might suggest thinking of 'pic') I think,
on the face of it, that it looks like a job that 'tbl' could handle
nicely, with a certain amount of "magic".

However, to get to that poiint (or with 'pic', in fact) I think the
data file should be filtered through (say) a suitable 'awk' program
to generate code that would produce the desired result. This would
depend on how the original data are presented.
