Answer 2

Bar charts can be used to compare the performance of two employees in the year 2016

Explanation:

A bar chart (sometimes known as a bar graph or a column chart) depicts numeric values for categorical feature levels as bars. On one chart axis, levels are drawn, while values are plotted on the other. Each bar represents a category value, and the length of each bar correlates to the value of the bar. To make it easier to compare values, bars are drawn on a similar baseline.

For comparisons, bar charts are useful. Bar graphs are used to compare two groupings of data or to follow changes over time.
