Conviction by Means of Visualization, Not Logics: Graphical Representation of Complex Numbers as a Way to Accept Their Existence Within Mathematics.

The eventual acceptance was due to their construction via graphical representations. What is revealing, moreover, is that this visual mode of conviction had been propagated not by famous mathematicians, but by persons marginal to the community.
