data visualization is the process of mapping ___ to ___
aesthetics
variables
two types of data
quantatative
qualatative
quantatative
continuous
discrete
numerical
qualatative
categorical
nominal (colour)
ordinal (rank it)
aesthetics (6)
position
shape
size
color
line width
line type
mapping variables to aesthetics
process by which we take data (qual or quant) and map it to visual elements ie, size, shape
mapping variables to aesthetics typically done through?
scale
ex, one day of time is equal to one pixel in the visualisation
position
all 2d data vis need to be positioned in some kid of space
common x,y coordinates
shape
shape = only discrete variables so often is used to represent categories
size
often mapped to amounts or magnitude
*shape and size often map together)
line width
often used to show amount or magnitude part “in time series” data
line type
like shape, line type can only represent categorical/qualitative data
three categories of colour scales
continous
categorical/qualitative
diverging
continuous colours
used to represent numerical/countable data
Makes use of our tendency to see colours as having higher or lower values
often a single hue (from dark to light blue)
qualitative colours
to distinguish between categories, we use qualatative colours
easily distinguishable (not close together in colour) - and have no apparent order
divering colours
where the values diverge around a midpoint (ie, percent trump/clinton supporters)
scale runs from saturated to light red, to a midpoint of white white then light to saturated blue
HSB
one framework to understand how to use colour
HSB: hue, satiration, brightness
hue
the colours of the spectrum
how we perceive colours hotter vs cooler
saturation
richness of a particular hue
used to make colours pop to draw attention to them
brightness
how bright colour is
what to think about?
who is the audeince?
what effect to achieve?
- represent data values faithfully
- persuade
- spark emotion/aethetic pleasing
- other reason specific ulitatian (ie, explain covid - made to do a job)

principle of data ink
principle of data ink
core idea is that good visual communication prioritizes clarity and efficiency by minimizing unnecessary elements while maximizing the amount of information conveyed in the graphical representation
