Dana provides ways to explore and display the recipe graph of Factorio (vanilla or modded). This mod is still in alpha stages: it is recommended to use it on a dedicated (sandbox) save, or at minimum to backup your save. While the mod should work in multiplayer, be careful about griefing (rendering huge graphs can freeze the game for several minutes).
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
