visualization

Etymology

It is formed from English visualize + -ation.^[2][3][4] Merriam-Webster treats it as an international scientific word.^[5] Visualize is formed from visual and -ize;^[2][3] Etymonline finds the verb in Coleridge's “Biographia Literaria” (1817) and suggests he may have coined it,^[3] while the OED's first record is from 1848.^[2] Visual is from Late Latin vīsuālis (“of sight”), from vīsus (“sight”), the past participle of videō (“to see”).^[6][3][2]

Semantic evolution

The word began as the mental act of picturing something, a sense now used especially of a meditative or therapeutic technique.^[2][4][6] In medicine, from 1900, it came to mean making a hidden organ or process visible, by X-rays, staining or surgery.^[2][5] From 1905 it also meant representing something in a visual medium, and in 1924, first in a textbook of industrial cost accounting, the presentation of data in charts, graphs and diagrams.^[2]
