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.

Explore the oldest underground in the world. Started in 1863, the London Tube today opens a new station inside ConceptDraw.

This spatial infographic example was created on the base of the tube map from the Transport for London website.

The vector stencils library "Transport maps" contains 34 shapes for designing the transportation maps, metro maps, subway maps, underground maps, tube maps using the ConceptDraw PRO diagramming and vector drawing software extended with the Metro Map solution from the Maps area of ConceptDraw Solution Park.

"A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system - whether this be bus lines, tramways, rapid transit, commuter rail or ferry routes. The main components are color coded lines to indicate each line or service, with named icons to indicate stations or stops. ...
There are a growing number of books, websites and works of art on the subject of urban rail and metro map design and use. There are now hundreds of examples of diagrams in an urban rail or metro map style that are used to represent everything from other transit networks like buses and national rail services to sewerage systems and Derbyshire public houses."

The transportation map template for the ConceptDraw PRO diagramming and vector drawing software is included in the Spatial Infographics solution from the area "What is Infographics" of ConceptDraw Solution Park.

The vector stencils library Map symbols contains 19 icons for labeling the maps using the ConceptDraw PRO diagramming and vector drawing software.
The vector stencils library Subway map contains 41 shapes for creating the subway (tube, metro) maps using the ConceptDraw PRO.
"The various features shown on a map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. Those signs are usually explained in the margin of the map, or on a separately published characteristic sheet.
Some cartographers prefer to make the map cover practically the entire screen or sheet of paper, leaving no room "outside" the map for information about the map as a whole. These cartographers typically place such information in an otherwise "blank" region "inside" the map -- cartouche, map legend, title, compass rose, bar scale, etc. In particular, some maps contain smaller "sub-maps" in otherwise blank regions—often one at a much smaller scale showing the whole globe and where the whole map fits on that globe, and a few showing "regions of interest" at a larger scale in order to show details that wouldn't otherwise fit."
