H Fabrice,
You did not provide a good minimum test because the graph by itself renders
fine:

(if all else fails, you can replace \startMPcode with \startMPpage and generate
a standalone graph that way)

Dear CTX wizards,
The commands given by Hans don't work properly in my case (with CTX on
Windows 11). I am probably ignorant of how to implement \startMPpage.

especially as I know how to make simple frames to include

Hi Floris,
directly generating SVG with ConTeXt LMTX is not possible.
But, using LMTX to generate SVGs has some advantages over MPOST.
You can use ConTeXt's advanced color management (transparency and more) and you
can use the very nice font management.
So my "metapost" file is:

How can I change the font size of labels within one picture?

\startMPpage
defaultfont := "\truefontname{Sans}";
defaultfontsize := \the\bodyfontsize;
label.top(defaultfontsize, (0,0));
defaultfontsize := 4bp;

Hi, I’m trying to understand MetaPost better.
I’d like to draw a fat line that’s cut at its end points.
I learned, “cutdraw” should do the trick, but I get a parallelogram
instead of a rectangle.
What’s wrong?
Hraban
\startMPpage
draw (0,20)--(20,20) withpen pensquare scaled 10;
cutdraw
. I'm guessing the way lmt_shade areas are
drawn is the way to go. Is this likely to be easy to code for what I
want to do?

Sorry, I misunderstood the question. Here is a solution (perhaps there is a
simpler solution !):

Like this ?
\startMPpage

and call that one instead of
passing through tex's tokenizer:
\startMPpage
input test.mp ;
\stopMPpage
then in order to save runtime do
