Render Array of colors

Hello, I was wondering if there was a way to render an array of colors. Say I have the following array and I want it to be rendered as a 3x3 square with the corresponding colors.

color_array = 
	[["#ffffff","#ff0000", "#ff0000"],
	["#ffffff","#ff0000", "#ff0000"],
	["#ffffff","#ff0000", "#ff0000"]]

My end goal is to show this metro map and update it with the real-time location of trains. I don’t know what would be the best way to make the map and my mind goes to updating arrays with the train location. I’m open to alternatives.


Could you just stack render.Plot() objects?

Yes, that looks to be the solution. Thanks!
