WRAPPING UP
At its core, visualization is an abstraction process to map data to color and
geometry. This is easy to do from a technical perspective. You can easily draw
and color shapes with a pencil and paper. The challenge is to figure out what
shapes and colors work best, where to put them, and how to size them.
To make the jump from data to visualization, you must know your ingredients.
A skilled chef doesn't just blindly throw ingredients in a pot, turn the stove
on high, and hope for the best. Instead, the chef gets to know how each
ingredient works together, which ones don't get along, and how long and at
what temperature to cook these ingredients.
With visualization, visual cues, coordinate systems, scales, and context are your
ingredients. Visual cues are the main thing that people see, and the coordinate
system and scale provide structure and a sense of space. Context breathes life
into the data and makes it understandable, relatable, and worth looking at.
Get to know how the components work, play with them, and get other people
to look at your results and see what information they extract.
