When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or ...
In the mathematical field of graph theory, the butterfly graph (also called the bowtie graph and the hourglass graph) is a planar, undirected graph with 5 vertices and 6 edges. [ 1 ] [ 2 ] It can be constructed by joining 2 copies of the cycle graph C 3 with a common vertex and is therefore isomorphic to the friendship graph F 2 .
[4] [5] Mosaic plots are also called Marimekko or Mekko charts because they resemble some Marimekko prints. [ 6 ] [ 7 ] However, in statistical applications, mosaic plots can be colored and shaded according to deviations from independence, whereas Marimekko charts are colored according to the category levels, as in the image.

[1] [2] The 7-page book graph of this type provides an example of a graph with no harmonious labeling. [2] A second type, which might be called a triangular book, is the complete tripartite graph K 1,1,p. It is a graph consisting of triangles sharing a common edge. [3] A book of this type is a split graph.
