Bar Chart
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 acolumn chart.

Bar graphs/charts provide a visual presentation of categorical data. Categorical data is a grouping of data into discrete groups, such as months of the year, age group, shoe sizes, and animals. These categories are usually qualitative. In a column (vertical) bar chart, categories appear along the horizontal axis and the height of the bar corresponds to the value of each category.

What is the difference between a histogram and a bar chart? There are two main differences:
1. For the histogram, you have to present the classes on the horizontal axis and the frequency on the vertical axis, whereas for the bar chart, you can present any variable on the axes.
2. The histogram has no gaps between the bars, whereas the bar chart does have gaps between the bars. Also, in the bar chart, bars can be represented vertically or horizontally.
