To provide the reader with a quick and visual way to analyze data
Explanation:
A graph is a type of diagram used to show the relation between variable quantities. There are several kinds of graphs, for example:
Line graph - illustrates how related data changes with time.
Bar graph - used to show categorical data with rectangular bars with heights proportional to the values they represent..
Pictograph - a representation of data using images.
Histogram - a graphical display of numerical data using bars of different heights.
Area graph - a graph based on the line graph but with the area below the line filled in with a certain color or texture.
Scatter plot - a graph that uses dots to represent values for two different numeric variables
The purpose of graphs in informational texts is to allow the reader to analyze data more easily and quickly. Visual content stands out more when it's surrounded by text, and sometimes it's impossible to quickly analyze data without these visual elements.
