2. n. A pictorial device, such as a pie chart or bar graph, used to illustrate quantitative relationships. Also called chart.
3. v. To represent by a graph.
4. v. To plot (a function) on a graph.
5. n. The spelling of a word.

Century Dictionary and Cyclopedia

1. n. A diagrammatic representation of a system of connections by means of a number of spots, which may be all distinguished from one another, some pairs of these spots being connected by lines all of which are of one kind. In this way any system of relationship may be represented. Graphs are commonly used in chemistry, and have been applied in algebra and in logic.
2. n. A terminal element in compounds of Greek origin, denoting that which writes, marks, or describes something, as in chronograph, telegraph, seismograph, etc., or, passively, that which is written, as in autograph, electrograph, etc. In the passive use the stricter form is -grammar
3. n. A curve as representing an equation or function.
4. n. A line drawn through a series of points whose position has been already determined.
5. n. A representation by points on or in a lattice.
6. n. The point of a link-motion which describes any curve.
7. To draw a curve representing (a given equation or function).
8. To trace graphs.
9. n. Any apparatus for duplicating drawings or writings by printing from a gelatinous surface.

Wiktionary

1. n. A diagram displaying data; in particular one showing the relationship between two or more quantities, measurements or indicative numbers that may or may not have a specific mathematical formula relating them to each other.
2. n. mathematics A diagram displaying data, in particular one showing the relationship between two or more variables; specifically, for a function , the set of all tuples .
3. n. graph theory An ordered pair , where is a set of elements called vertices (or nodes) and is a set of pairs of elements of , called edges; informally, a set of vertices together with a set edges that join these vertices.
4. v. transitive To draw a graph.
5. v. transitive, mathematics To draw a graph of a function.

GNU Webster's 1913

1. n. (Math.) A curve or surface, the locus of a point whose coördinates are the variables in the equation of the locus.
2. n. A diagram symbolizing a system of interrelations of variable quantities using points represented by spots, or by lines to represent the relations of continuous variables. More than one set of interrelations may be presented on one graph, in which case the spots or lines are typically distinguishable from each other, as by color, shape, thickness, continuity, etc. A diagram in which relationships between variables are represented by other visual means is sometimes called a graph, as in a bar graph, but may also be called a chart.
