How to pass parameters to the specified JSL in the graph fetch?

[#1]

Examples in the index of software

dt = Open( "$SAMPLE_DATA/Big Class Families.jmp" );
gb = dt << Graph Builder( Show Control Panel( 0 ), Variables( X( :age ), Y( :weight ) ), Elements( Bar( X, Y, Legend( 7 ) ) ));
frame = (gb << report)[FrameBox( 1 )];
frame << Set Graphlet( Picture(  loader = Include( "$BUILTIN_SCRIPTS/hllib.jsl" );  hlp = loader:lazyLoad( "hllPresets" );  hlp:launchPie(); ), Title( "Pie Preset" ), Reapply( 1 ));

How does it pass parameters to hllib.jsl?
Which variable name is it in hllib.jsl?

Thanks!
