The Río Grijalva and its continuation, the Cuilco, rendered as an urban transit network. River names change frequently in Mexico and Guatemala (especially at the border between the two), and so there are quite a lot of compound names. I’ve tried to cover every name that a stream has through its course. Good data for Guatemala are also hard to come by, so I’ve kept things a bit sparser there, preferring to go with only what I could confirm.
