Gantt chart
Some trip planners integrate information services other than point-to-point trip planning into their user interface, for example to provide timetables for routes, real-time arrivals and departures at stops, or real-time disruption notices. Additional visualizations may be offered; Google, for example, has a Gantt chart like 'Schedule explorer' that can be used to visualize the relative timings of different trip plans. Another powerful visualization is the Isochrone map which shows relative travel times as relative distances.
