How to draw Metro Map style infographics? (London)

"The Tube map is a schematic transit map of the lines and stations of London's public rapid transit railway systems, namely the London Underground (commonly known as the Tube, hence the name), Docklands Light Railway, London Overground and Emirates Air Line, as well as being incorporated into Greater London connections maps.
As a schematic diagram, it shows not necessarily the geographic but rather the relative positions of stations along the lines, stations' connective relations with each other and fare zones. The basic design concepts have been widely adopted for other network maps around the world, especially that of mapping topologically rather than geographically." [Tube map. Wikipedia]
The transit map example "London tube map" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Metro Map solution from the Maps area of ConceptDraw Solution Park.
