I’ve often come across grapviz and the DOT notation, and was thinking it would be pretty cool and potentially very useful to be able to create maps in tinderbox and export for re-use (i.e. in RStudio / RMarkdown).
The export would most definitely not “carry” all attributes of the map (i.e. note text), and visually it would not be true to the map in Tinderbox, but it is a -perhaps edge- solution for exchanging information of this type (diagrams etc.).
