A curvaceous, minimalist diagram. Notably mainly for the strangely muted colour scheme (yellow, brown and purple?) and the interesting interchange station symbols, which make things very clear by showing two arrows pointing in opposite directions. Visually, I like the way that the diagram makes use of overprinting where the route lines overlap.
Update: I’ve since found out that this map is a small inset on a much larger geographical map of bus services in Leningrad, which explains its simplicity somewhat.
Our rating: Simple but effective! There’s a pleasing organic feel to the route lines that I can’t help but like. Three stars.
