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, but various heuristics, such as algorithms that plot data as the maximal ...
Paintings of Araneus angulatus from Svenska Spindlar of 1757, the first major work on spider taxonomy. Spider taxonomy is the part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida, which has more than 48,500 described species.

A radar chart or "spider chart" or "doi" is a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. A waterfall chart also known as a "Walk" chart, is a special type of floating-column chart. A tree map where the areas of the rectangles correspond to values. Other dimensions can be ...

SPIDER is an interferometric ultrashort pulse measurement technique in the frequency domain based on spectral shearing interferometry.Spectral shearing interferometry is similar in concept to lateral shearing interferometry, except the shearing is performed in the frequency domain.
One study estimates that the global average spider density is 131 spiders per square meter. Obviously, habitats like deserts have fewer spiders, but others have spider densities of 1,000 per ...
The common rain spider (Palystes superciliosus), formerly P. natalius, [1] is a species of huntsman spider native to Southern Africa. [2] It is the most common and widespread species in the genus Palystes . [ 3 ]
