3. A dreaded pie chart
3D!
No title – not even on
the original graphic –
it is assumed the
viewers kept on
reading to
understand what this
graphic is visualizing
Difficult to understand
at first glance
Dull colors
Labeling looks
awkward because it
varies among
different pie slices
Numbers add to 100%,
but order by employee
size is not inherently
understood
No attention is drawn
to the important
aspects of the data
Key looks out of place
and small compared to
the chart
BREAK IT DOWN
