A bar chart is a chart that represents data with categories to their associated values. This type of chart can be vertical or horizontal depending upon the ease of visualization. In a bar chart, we keep categories on one axis while its corresponding values on the other.
Why do you need it?
We need a bar chart to have a meaningful visual of the uncertain data that we get in the form of a table or an excel file. The bar chart divides the data into categories that are easy to understand by the human brain. Using a bar chart makes the analysis of data a cup of tea for profitable outcomes.
What kind of data you can visualize with it?
A bar chart best suits data that is category-related. Assume you have a dataset that has categories of T.V series like comedy, drama, action, romance, sci-fi, etc. and the number of audiences per category then we can use a bar chart.
