Construction impassionata

An early stab at the building graph overlaid on the technology graph:

Cleaned up, using groups for technology nodes and heavy solid lines for the tech tree, dashed lines for products_needed_to_build and solid lines for inputs_to-produce:

buildings-1

There’s still much to do. I’m also thinking about dropping out a whole technology level – feels like there are too many acts in the play.
