Comparison of proportion (part of a whole)

100% stacked bar chart

People have an easier time interpreting perpendicular angles and segment lengths, so 100% stacked bar graphs are a superior option over pie charts to visualize proportion [7, 8].

2

Trend over time with target

Line graph with target

A line graph is the simplest way to visualize change over time and humans have an easy time judging changes in slope [7, 8, 11, 12]. Target is marked at one point to increase dataink ratio [11].

Comparison of proportion

Stacked bar chart

People have an easier time interpreting perpendicular angles and segment lengths, so 100% stacked bar graphs are a superior option over pie charts to visualize comparisons of proportions [7, 8]. A stacked bar is one technique used to visualize results modelled by the Lives Saved Tool (LiST) [35, 36].

4

Trend over time with uncertainty

Line graph with confidence interval bars

A line graph is the simplest way to visualize change over time and humans have an easy time judging changes in slope [7, 8, 11, 12]. Error bands is one approach to visualize uncertainty [8, 34].

5

Geographic performance

Maps

Maps are used to represent geospatial data [8, 11, 12].
