Important Components of Visualization

Symbols: Circles, dots, lines, bars, ...
Position: Axes and the origin (0/0) are important.
Size/Area: Should only be used if it faithfully

represents information.

Color: One color should not overpower another.
Angle: Human eyes are not good at comparing

angles.

All components of the plot need to convey
information. E.g., don’t use color just to make it

more colorful.
