I created a website to visually showcase Factorio blueprints. You can import blueprints as text and adjust drawing settings or generate random designs. Everything, from buildings to connections, is displayed using vector graphics for high resolution viewing. Note that blueprints from versions before Factorio 2.0 may have issues, but can be updated by importing and exporting them again. This tool can be used for text-to-image neural network fine-tuning or pen plotting. Other Factorio tools are available, like Factorio SAT for optimal belt layouts. Contributions and bug reports are encouraged. Check out the website for stats on visitor traffic.
