A chart can help you examine a large amount of data in just a few pictures. For example, a pie chart helps you gather all the information and then find the percentage amount of the thing you are looking for. 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. There are many more charts, these are just two that help you a lot more than you think.
