给定一个数据集，它将取得所有轨道/站点的关系。

图片利用 Visualizing the tube in D3实现。

命令行工具

目前命令行只支持伦敦

$ tubemaps path  --from "Euston" --to "Hammersmith"  # Victoria Line: Euston to Warren Street  # Victoria Line: Warren Street to Oxford Circus  # Victoria Line: Oxford Circus to Green Park  # Victoria Line: Green Park to Victoria  # Victoria Line: Victoria to Sloane Square  # District Line: Sloane Square to South Kensington  # Piccadilly Line: South Kensington to Gloucester Road  # Piccadilly Line: Gloucester Road to Earl's Court  # District Line: Earl's Court to Barons Court  # Piccadilly Line: Barons Court to Hammersmith    $ tubemaps station "Euston" --london                      # Northern Line: Camden Town  # Victoria Line: King's Cross St. Pancras  # Northern Line: Mornington Crescent  # Victoria Line: Warren Street  # Victoria Line: King's Cross St. Pancras  # Victoria Line: Warren Street

现有数据集

伦敦

var Maps = require('tubemaps/maps');    Maps("london", function(err, tube) {    var euston = tube.getStationByName("Euston");    var victoria = tube.getStationByName("Victoria");    console.log(tube.path(euston, victoria))  })
