Question

where did pie chart and area chart is used?​

Answer 1

Answer:

pie chart

Explanation:

this chart shows the proportional size of

items that make up a data series to the sum of the items .it always shows one data series.this is a circular chart which

specifies each data value when compared to totaly.

area chart:

• this chart emphasizes the magnitude of change over time .by displaying the sum of the plotted values,an area chart also shows relationship of parts to the whole.

Answer 2

Explanation:

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. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801.[1][2]

Pie charts can be replaced in most cases by other plots such as the bar chart, box plot, dot plot, etc.

Information in an area chart is plotted on the x- and y-axis; data values are plotted using data points that are connected using line segments.
