What is pie chart explain with example?

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.

What is better than a pie chart?

Simple bar chart or Stacked bar chart Definitely, the best alternative for a pie chart/ donut chart is a simple bar graph because in that case we only have to compare one dimension, length with more clarity and less cutter.

The basic premise is that pie charts are poor at communicating data. They take up more space and are harder to read than the alternatives. The brain’s not very good at comparing the size of angles and because there’s no scale, reading accurate values is difficult.

How do you explain a pie chart?

A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole.
