It works because of the "pair z” statement. Attempted explanation:
Metapost variable names are built up hierarchically. When you

I'd like to know
if there are (reasonable) demands for more graphics support using
metapost. Alan and I are on-and-off working on some extensions and one
of the things we discuss is visualization of data. The question is of
course what should be done in the lua/mp/tex combination and
one,
since other slides are not considered as subsubsections.
If I stick to this, should I use subsubsection as a default which it's
derived from.

be a way to insert automatically key to symbols under the met
The content of all mentioned modules has moved to the core years ago
and there is no need to load another code although a few goodies like
fancy arrow styles etc. (which use metapost graphics) have to loaded.
To get a proper answer to your problems you should provide a example

The code is fairly fast. But be careful. As with all ConTeXt key-value

lazy here, and haven't adapted the metapost code to draw the axes to adapt
to the function.

Ha
Wow! This is cool!
I must admit I do not get how the connections between MetaPost and Lua
works, but it seem to work fine.

macro expansion, which can be very expensive for large loops.

The closest I have found which is something MetaPost-like, is the
levelcurve command in mfpic (see for example this answer
https://tex.stackexchange.com/a/405527/52406).
If this is not currently possible in MetaFun, what is the simplest way
to proceed (I want the same style of
de to generate the step response in
Lua/Metapost. But it quickly gets tiring and one essentially ends up creating
a domain specific computational library in Lua.
An alternative approach, is to use an existing library written in some other
programming language (say Matlab or R or Julia or whatever).
