A pie chart displays the size of each item in a data series in proportion to the total sum of the items. A data series refers to the related data points plotted in a chart, which originate from rows or columns in a data table. Each data series in a chart has a unique color or pattern and is represented in the chart's legend. One or multiple data series can be plotted in a chart, but a pie chart only has one data series.
Input

The first column contains data names, the second column contains values, separated by a tab character (\t) in between.
Output
