Reading #4

1. In the line graph figure, the decline appears more substantial than it actually is because the axis does not go to 0 (therefore, the line looks steeper). If that is the case, why does the idea of “proportional ink” matter?

2. If a donut chart uses a track style graph that has more length on the outer rings, when would such a chart be effective and accurate?

3. When/is it ok to sacrifice accuracy for more effective visual perception?
