The code and more examples are available here: https://github.com/piebro/factorio-blueprint-visualizer, and the website where you can create your own visualizations is here: https://piebro.github.io/factorio-blueprint-visualizer/. Last year, I also printed some of these to hang them in my room and gift them to friends and relatives for Christmas. Feel free to post feedback or your creations here if you like
