2. Time–distance diagram - Wikipedia

   en.wikipedia.org/wiki/Time–distance_diagram

   A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...

3. Distance-transitive graph - Wikipedia

   en.wikipedia.org/wiki/Distance-transitive_graph

   In the mathematical field of graph theory, a distance-transitive graph is a graph such that, given any two vertices v and w at any distance i, and any other two vertices x and y at the same distance, there is an automorphism of the graph that carries v to x and w to y. Distance-transitive graphs were first defined in 1971 by Norman L. Biggs and ...

5. Distance (graph theory) - Wikipedia

   en.wikipedia.org/wiki/Distance_(graph_theory)

   The latter may occur even if the distance in the other direction between the same two vertices is defined. In the mathematical field of graph theory, the distance between two vertices in a graph is the number of edges in a shortest path (also called a graph geodesic) connecting them. This is also known as the geodesic distance or shortest-path ...

6. Spacetime diagram - Wikipedia

   en.wikipedia.org/wiki/Spacetime_diagram

   At its most basic level, a spacetime diagram is merely a time vs position graph, with the directions of the axes in a usual p-t graph exchanged; that is, the vertical axis refers to temporal and the horizontal axis to spatial coordinate values.

7. Travel-time curve - Wikipedia

   en.wikipedia.org/wiki/Travel-time_curve

   Travel-time curve is a graph showing the relationship between the distance from the epicenter to the observation point and the travel time. [2] [3] Travel-time curve is drawn when the vertical axis of the graph is the travel time and the horizontal axis is the epicenter distance of each observation point. [4] [5] [6]

8. Distance-regular graph - Wikipedia

   en.wikipedia.org/wiki/Distance-regular_graph

   The 13 distinct cubic distance-regular graphs are K 4 (or Tetrahedral graph), K 3,3, the Petersen graph, the Cubical graph, the Heawood graph, the Pappus graph, the Coxeter graph, the Tutte–Coxeter graph, the Dodecahedral graph, the Desargues graph, Tutte 12-cage, the Biggs–Smith graph, and the Foster graph.

9. Unit distance graph - Wikipedia

   en.wikipedia.org/wiki/Unit_distance_graph

   Where the terminology may be ambiguous, the graphs in which non-edges must be a non-unit distance apart may be called strict unit distance graphs [3] or faithful unit distance graphs. [2] The subgraphs of unit distance graphs are equivalently the graphs that can be drawn in the plane using only one edge length. [ 4 ]
