visual design theory Flashcards
what makes up for poor graphical integrity
design variation, lack of context, graphical distortion
how to measure graphical distortion
lie factor = size in graph/size in data
how to prevent graphical distortion
clear, detailed labelling to prevent graphical distortion and ambiguity
why is design variation bad
leads to deception, eye may mix up what it sees
what is an important point from design variation
show data variation and not design variation
what are the components of visual design theory
data ink, chart junk, data density
what is an important point from data ink
maximise data ink, erase non-data ink, erase redundant data ink
what are examples of chartjunk
unintentional optic art, grids, self-promoting graphics
what is the formula for data density
data density = number of entries in data matrix/area of data graphic
what is an important point form data density
maximise data density and the size of the data matrix
how to maximise data density and size of data matrix
words, numbers and pictures. if shape of data is given, use it. if not follow horizontal configuration
what are some important considerations
visual encoding, interaction, colour, context
what makes up visual encoding
visual marks, visual channels
what are some examples of visual marks
points, lines and areas (represent the object)
what are some examples of visual channels
shape, size, area, colour, tilt, volume
