Which chart type is best for showing the parts of a whole?

A pie chart is the most effective chart type for illustrating the proportional distribution of data within a single series. Each slice of the pie represents a category's contribution to the total sum, making it the standard and most direct way to visualize the "parts of a whole." This is useful for scenarios like showing percentage breakdowns of a budget, survey results, or market share where the sum of the parts equals 100%.

A. Scatter Chart: This chart is used to show the relationship and correlation between two different sets of numerical data, not the proportional parts of a single total.

B. Column Chart: This chart is best for comparing discrete values across different categories, rather than showing the composition of a single whole.

D. Line Chart: This chart is designed to display trends and changes in data over a continuous interval, such as time, not for representing static proportions.

it states

"Pie charts show the size of items in one data series

proportional to the sum of the items... Use a pie chart when: You only have one data series. None of the values you want to plot are negative... Your values can be converted to percentages of a whole."

the guide specifies

"To show parts of a whole

you can use: Pie Chart... A pie chart represents the share of each value out of a total."

"Circle graphs

or pie charts

are used to represent the parts of a whole."
