How to draw a polygon with outline?

[#1]

I have a piece of script that draws a polygon.

It has semi-transparent fill, but I'd rather have just line outline. How do I do that?

	framebox << Add Graphics Script(
		Transparency( 0.5 );
		Fill Color("Green");
		Polygon( {246, 37}, {246, 437}, {772, 437}, {772, 37} );
                //Command for an outline?
	);

What do you get with this version:

framebox << Add Graphics Script(
	Polygon( {246, 37}, {246, 437}, {772, 437}, {772, 37} );
);

I'm getting dark violet polygon, no outline.
I think I'll just use Line(); instead.

Sorry, I forgot that the Polygon() graphics function renders filled shapes. Use Line() function instead.

Names Default to Here( 1 );

New Window( "Draw My Polygon",
	Outline Box( "Polygon",
		Graph Box(
			Line(
				{ 10, 10 },
				{ 50, 10 },
				{ 90, 50 },
				{ 50, 90 },
				{ 10, 10 }
			)
		)
	)
);
