A biplot is constructed by using the singular value decomposition (SVD) to obtain a low-rank approximation to a transformed version of the data matrix X, whose n rows are the samples (also called the cases, or objects), and whose p columns are the variables.
A biplot is in fact a low dimensional mapping of a part of the information contained in the original table. As a rule of thumb that set (rows or columns) which should be analysed with respect to its composition as measured by the other set is displayed in principal coordinates while the other set is displayed in standard coordinates.
A generalised biplot displays information on both continuous and categorical variables. Bland–Altman plot : In analytical chemistry and biostatistics this plot is a method of data plotting used in analysing the agreement between two different assays .
Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
Biplot of the Principal components analysis of Anderson's Iris data set. The SVG was created with R's biplot function using the CairoSVG device of the Cairo R package: Date: 24 September 2008: Source: I created this work entirely by myself. Author: Calimo: SVG development
Replica of a Chappe telegraph on the Litermont near Nalbach, Germany. Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message.

"The application and development of the biplot and its associated decomposition utilized in this paper follows from the work of Gabriel (1971, 1972a, b)." "The biplot shows that river systems within a basin form distinct clusters which are related to their water quality.
