2. The metafun alternative is a bit inconvenient. Suppose you want to
draw a bunch of such graphics (words connected by arrows). Then, you
will need to ensure that node names are unique. (Is there a way to get
around that?)
\newcounter\connectedwordcounter
\starttexdefinition unexpanded fromword [#1]#2
    \expandafter\pushmacro\csname cwc>#1\endcsname % nesting hack
    \doglobal\increment\connectedwordcounter
    \setxvalue{cwc>#1}{\connectedwordcounter}%
    \startpositionoverlay{highlightoverlay}
        \setMPpositiongraphic
          {\getvalue{cwc>#1}>f}
          {highlightgraphic}
          {from=\getvalue{cwc>#1}>f,to=\getvalue{cwc>#1}>t}
    \stoppositionoverlay
    \hpos{\getvalue{cwc>#1}>f}{#2}%
\stoptexdefinition
\starttexdefinition unexpanded toword [#1]#2
    \hpos{\getvalue{cwc>#1}>t}{#2}
    \expandafter\popmacro\csname cwc>#1\endcsname % nesting hack
\stoptexdefinition
Thanks.
