Types of graphs/charts

There are many Types of graphs or charts you can use in order to organize your information. I use charts and graphs because it is easier for me to visualize data and information. Its a good way to divide information and i think it looks better with different colors and forms.

In addition, it is a very good way to summarize the information. I use graphics in order to display the most relevant information and make emphasis on the most important data as total, average etc. There are several types of charts and this makes it easier to find the right one to display any type of information and make it clearer.
