    line A synonym for an undirected edge. The line graph L(G) of a graph G is a graph with a vertex for each edge of G and an edge for each pair of edges that share an endpoint in G. linkage A synonym for degeneracy. list 1. An adjacency list is a computer representation of graphs for use in graph algorithms. 2.

    visual information device : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. specific kind of visual display : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links.

  4. Line graph - Wikipedia

    en.wikipedia.org/wiki/Line_graph

    In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G. L(G) is constructed in the following way: for each edge in G, make a vertex in L(G); for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L(G).

    The R programming language can be used for creating Wikipedia graphs. The Google Chart API allows a variety of graphs to be created. Livegap Charts creates line, bar, spider, polar-area and pie charts, and can export them as images without needing to download any tools. Veusz is a free scientific graphing tool that can produce 2D and 3D plots ...

  6. Graph (discrete mathematics) - Wikipedia

    en.wikipedia.org/wiki/Graph_(discrete_mathematics)

    A path graph or linear graph of order n ≥ 2 is a graph in which the vertices can be listed in an order v 1, v 2, …, v n such that the edges are the {v i, v i+1} where i = 1, 2, …, n − 1. Path graphs can be characterized as connected graphs in which the degree of all but two vertices is 2 and the degree of the two remaining vertices is 1.

  7. Misleading graph - Wikipedia

    en.wikipedia.org/wiki/Misleading_graph

    Both graphs show an identical exponential function of f(x) = 2 x. The graph on the left uses a linear scale, showing clearly an exponential trend. The graph on the right, however uses a logarithmic scale, which generates a straight line. If the graph viewer were not aware of this, the graph would appear to show a linear trend.

  8. Hypernymy and hyponymy - Wikipedia

    en.wikipedia.org/wiki/Hypernymy_and_hyponymy

    The meaning relation between hyponyms and hypernyms applies to lexical items of the same word class (that is, part of speech), and holds between senses rather than words. For instance, the word screwdriver used in the previous example refers to the screwdriver tool, and not to the screwdriver drink. Hypernymy and hyponymy are converse relations.

  9. Graphomania - Wikipedia

    en.wikipedia.org/wiki/Graphomania

    Graphomania is related to typomania, which is obsessiveness with seeing one's name in publication or with writing for being published, excessive symbolism or typology. [7] Outside the psychiatric definitions of graphomania and related conditions, the word is used more broadly to label the urge and need to write excessively, professionally or not.
