Answer:
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.Simple bar diagram is the type of the chart which shows the values of the different categories of data as the rectangular bars with the different lengths whereas in the multiple bar diagrams the data sets are represented by drawing the bars side by side in a cluster.
