(astronomy) Abbreviation of Hertzsprung-Russell diagram.

A flow diagram in which the width of the arrows is proportional to the flow rate.

(astronomy) A diagram, used to illustrate the Hubble law, in which the velocity of an object (assumed to be approximately proportional to its redshift) is plotted with respect to its distance from the observer.

(mathematics) A graph with some edges drawn as double or triple lines, arising in the classification of semisimple Lie algebras over algebraically closed fields, in the classification of Weyl groups and other finite reflection groups, and in other contexts.

A type of Cartesian graph where each axis represents a different variable, and opposite directions along an axis represent different quantities rather than positive or negative signs of the same quantity; thus four variables are diagrammed in total.

Synonym of radar chart

(geology, geochronology) Any of several types of diagram, used in connection with uranium–lead dating, in which each axis encodes differently sourced information about the radiometric age of the mineral being dated.

(geology, geochronology) A type of concordia diagram, used in the context of uranium–lead dating, whose axes are the ratios ²⁰⁶Pb/²³⁸U and ²³⁷Pb/²³⁵Pb.
