A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative.

Similar to a regular square treemap, but convex polygons are used instead of rectangles e.g. a new hierarchical partition scheme, also called a polygonal partition, which uses convex polygons rather than just rectangles.
Treemaps display hierarchical (tree-structured) data as a set of nested polygons. Each branch of the tree is given a polygons, which is then tiled with smaller polygons representing sub-branches.
The use of Convex Treemaps compared to regular tree maps would be when you want to show grouping and realtions instead of the strict hierachical structure of a a normal treemap.

Polar chart displays multivariate data in the form of a two-dimensional chart of more than three variables represented on axes starting from the same point.

Y-Matrix is one of six forms of Matrix Diagram. A Matrix Diagram shows the relationship between items. At each intersection a relationship is either absent or present. It then gives information about the relationship, such as its strength, the roles played by various individuals or measurements. It can be shaped differently depending on how many groups must be compared. The other five differently shaped matrices are: L, T, X, C, R and roof-shaped.

Hexagonal Binning is another way to manage the problem of having to many points that start to overlap. Hexagonal binning plots density, rather than points. Points are binned into gridded hexagons and distribution (the number of points per hexagon) is displayed using either the color or the area of the hexagons.This technique was first described in 1987 (D.B.Carr et al. Scatterplot Matrix Techniques for large N, Journal of the American Statistical Association, No.389 pp 424-436).
There are many reasons for using hexagons instead of squares for binning a 2D surface as a plane. The most evident is that hexagons are more similar to circle than square. This translates in more efficient data aggregation around the bin center. This can be seen by looking at some particular properties of hexagons and, especially, of the hexagonal tessellation.

In addition to the Ternary Plot, you will also find the Ternary Contour Plot. These plots can be used for example to chart the response of an independent variable to changes in a mixture of three components.

A bagplot is a method in robust statistics for visualizing two-dimensional statistical data. The bagplot allows one to visualize the location, spread, skewness, and outliers of the data set. The bagplot consists of three nested polygons, called the “bag”, the “fence”, and the “loop”. The bagplot is sometimes defined as the multidimensional (bivariate) version of the box plot.


A ternary plot is a barycentric plot on three variables which sum to a constant. It graphically depicts the ratios of the three variables as positions in an equilateral triangle. It is used in physical chemistry, petrology, mineralogy, metallurgy, and other physical sciences to show the compositions of systems composed of three species.

The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged. The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike chemical formulas, which have a limited number of symbols and are capable of only limited descriptive power, structural formulas provide a complete geometric representation of the molecular structure
