When dealing with categorical datas, you should use bar graphs as it organizes data by categories. However, when you are dealing with numerical datas, you should use a histogram to investigate the distribution of those datas.
The main feature you can look at to identify the type of the graph is by examining it whether there are spaces between bars. If there is no space between bars, it is likely a histogram. However, if there are spaces between bars, it is likely a bar graph.
