The center (or Jordan center [1]) of a graph is the set of all vertices of minimum eccentricity, [2] that is, the set of all vertices u where the greatest distance d(u,v) to other vertices v is minimal. Equivalently, it is the set of vertices with eccentricity equal to the graph's radius. [3]

Given a graph, the eccentricity of a vertex v is defined as the greatest distance from v to any other vertex. A center of a graph is a vertex with minimal eccentricity. A graph can have an arbitrary number of centers. However, Jordan (1869) has proved that for trees, there are only two possibilities: The tree has precisely one center (centered ...
Center (geometry), the middle of an object; Center (algebra), used in various contexts Center (group theory) Center (ring theory) Graph center, the set of all vertices of minimum eccentricity; Central tendency, measures of the central tendency (center) in a set of data
The graphs include bar charts, pie charts, line charts, area charts, scatter plots, tag clouds, tree maps, and political maps. Bar/line/area charts can be easily created by using Template:Graph:Chart ; the documentation for this template explains its functions and use in extreme detail.
