The introduction is very simple and sets the objective of the paper. In a simple manner it uses the analogy of encoding the data to be represented and how we perceive it as decoding. So is is an experiment to analyze the decoding process in detail.
It mainly focuses on these
(1) Position along a common scale.
(2) Position along identical but non-aligned scales.
(3) Length.
(4) Angle.
(5) Slope.
(6) Area.
There is an experiment conducted focusing on these aspects and how it matters.
The experiments in graphical perception help in improving the display of data.
It shows that by our choice of the graphical methods we use to show data, we can control,to some extent, the basic judgments that are required to decode quantitative information.
