Graphs give a very rapid visual of trends that may exist in data. This trend may be observed and formulae may be derived based on proportionality of 2 variables (one being controlled at a time)
it just a straight line
graphs are to compare and contrast data
Graphs are diagrams that show information in a clear and simple way.
bar graphs are used to compare different data. a line graph is used to see the changes over a period of time of a specific data. a circle graph is used to represent a part to a whole relationship.
Graphs show the relationship of one quantity to another. For example, it may show how the density of a material changes when the temperature is increased, or it may show the inflation depending on time. Vertically you show the quantity of interest (density, inflation) and horizontally what it depends on (temperature, time). You measure / look up / guess for each temperature the density, and draw a dot which is above the given temperature and to the right of the given density, and you do that for many densities.
I can only think of one drawback to graphs, and that is that some people don't understand them. They are used because they have so many advantages. There are several educational initiatives which help the proper understanding of graphs.
There are a few good things about graphs. Graphs help gather data making it easier for people to short things out.
U just have to poop
graphs allow for an alternative visual method to solve mathematical equations.
Line graphs are often more clear to analyze, and are used for continuous data. bar graphs are used for just a certain amount of results, ones that don't continue.

bar graphs
Visual representation of numbers and figures, to see proportion.
Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.
Graphs can be used at home, especially if you're remodeling.
