graph label

[tfiers]

.. with version of root pkg :)

(if a setting: either a function (given package name, or some info struct); or a mustache/jinja/handlebars like {{template}} string)
(same as for emptymsg)

For

• Measure load times; display on graph #64:

can display versioninfo() like stuff :) (cause it's important for scale of measurements)

How-to is just, it seems:

digraph {
  label = ".."
}

So, gathering above backlinks, what should go in graph 'label':

• Version of root package
• Whether from active project (manifest), or General registry
• maybe: date generated :)
  • Also! PkgGraph.jl & its version :)
    • Ooh, in SVG, could link to repo :)
• Whether and how many stdlib & jll packages hidden
  • No need to say "to unhide, pass ..": can say that in REPL :)
  • Btw, to give these numbers -- and to make the heuristic decision! -- we do need to crawl for them! (I.e. can't early stop in tree search in depgraph)
• If timing: @time of total import. (And colour for how bearable that is)
  • Also: versioninfo()-like info, to give context to the timing numbers
    • maaaybe could use https://github.com/giampaolo/psutil (via Conda.jl or sth) to get current system load. but that's a bit silly (https://discourse.julialang.org/t/get-cpu-usage/24468/2)
    • Oh, actually, it is short indeed, and Sys.cpu_info() (note lowercase) works.

      Ok, so is feasible :)

so yeah, this should be a html-like block, can't just be a string w/ newlines.
Can a graph's label be that? Or do we need to create a floating node.
Stichtend voorbeeld: https://graphviz.org/Gallery/directed/pprof.html
(is geen html, gewoon text; maar kan daar perfect i'm sure)
a subgraph.. Necessary? or is node in main graph ('cluster') good too

Dependency graph for Plots v0.7.2

145 packages, of which 42 standard library and 66 JLL packages were filtered out.

Or, if not even crawling them:

Dependency graph for Plots v0.7.2

32 packages, not including standard library and JLL dependencies
