Hi,

You could just convert these separately to pdf/svg/jpg/png and then load them as \externalfigure. 

You could also use the filter module to be able to take them inline into the ConTeXt code:


\usemodule[filter]

\define[1]\ReadFigure{\externalfigure[#1]}
    
\defineexternalfilter[graphviz]
  [cache=yes,
   readcommand=\ReadFigure,
   output={\externalfilterbasefile.pdf},
   filtercommand={dot -Tpdf -o "\externalfilterbasefile.pdf" "\externalfilterinputfile"}]
  
\starttext
\startTEXpage
\startgraphviz
digraph G {
    main -> parse -> execute;
    main -> init;
    main -> cleanup;
    execute -> make_string;
    execute -> printf
    init -> make_string;
    main -> printf;
    execute -> compare;
}
\stopgraphviz
\stopTEXpage
\stoptext


See the filter module documentation for more details about that.

Best wishes,
Taco
