Visibility graph analysis
(VGA) is a method of analysing the inter-visibility connections within buildings or urban networks
. Visibility graph analysis was developed from the architectural theory of space syntax
by Turner et al (2001), and is applied through construction of a visibility graph
within the open space of a plan.
Visibility graph analysis uses various measures from the theory of small-world networks and centrality in network theory in order to assess perceptual qualities of space and the possible usage of it.
