Why are graphs and charts used to represent information?
Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. It is important to provide a clear and descriptive legend for each graph.
What are the advantages of using charts and graphs?
The advantage to using graphs and charts is that they can display a lot of information is an easy to understand format. For example, a line graph is a great way to show trends over a period of time. You could put numbers in a table, but a line that is consistently going up is much more accessible at a quick glance.
What are the disadvantages of using charts and graphs?
The major disadvantage of using charts and graphs is that these aids may oversimplify data, which can provide a misleading view of the data. Attempting to correct this can make charts overly complex, which can make their value in aiding a presentation less useful.
What is the benefit of using a graph?

What are the disadvantages of graphs?
Disadvantages:Doesn’t reveal exact values.Multiple graphs are needed for time-lapse data.Key assumptions, causes, effect, and patterns are not revealed.Manipulated easily, causing false impressions or interpretations.
What are the advantages and disadvantages of using charts and graphs?
Advantages: summarize a large dataset in visual form; easily compare two or three data sets; better clarify trends than do tables; estimate key values at a glance. Disadvantages: require additional written or verbal explanation; can be easily manipulated to give false impressions.
What is the advantage of a bar graph?

Why do we have different types of graphs?
