The term GRAPH PATTERN can be broken down into two parts: GRID (4 letters) and PATTERN. A GRID is a two-dimensional structure made up of intersecting lines, usually in the form of a square or rectangle. It is used to organize information into rows and columns. A PATTERN is a regular arrangement of shapes, lines, or colors that is repeated over and over again. When combined, a graph PATTERN is a visual representation of data that uses a GRID to display patterns. Graph patterns are often used to show trends or relationships between different variables.
