Factorio – Visualizing construction material dependencies

Good graphs, but if possible I'd have put labels on the edges showing resource required per second or something like that to keep the production line running. Some of these need a lot more iron than others.

Then you can go figure out how many iron ore mining drills you need to keep a purple science factory running.

http://doomeer.com/factorio does that. You can specify how many of each product you want to produce per second, minute or hour and it shows how many assemblers and what raw material production is required.

That's starting to sound like State Task Networks/Resource Task Networks from production process design/scheduling.

high-end factorio is all about process design/scheduling, IMO...
