im kinda guessing but i think its because sometimes there are certain charts you need to use when solving a problem :)= (math or any other thing or subject)=
Pie graphs are good for showing a percent of something.
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.
Pie graphs are used when a part of something total is represented in relation to the whole thing
pie graphs show volume and are good for showing the relationship of size. line graphs are good for showing trends which can lead to predictions.
b the pie graph is circle ok
Pie Graphs, Bar Graphs, and Line Graphs are three graphs that scientist use often.

There are many graphs which while you can usually use most of them no matter what experiment you are doing that is not always true, nor is it the right use of a graph. some of the most likely graphs you will probably come across , or for that matter need to use are bar graphs, line graphs, pie graphs, and picture graphs.

Bar graphs, pie charts, and even line graphs can all be used to compare. I personally like to use Bar graphs when showing numbers.
You can use pie charts, line graphs, bar graphs and scatter point graphs to present data.
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.

Bar graphs show an '''amount''' of data. Line graphs show data '''over time.''' Pie graphs show a '''percentage''' in the data.
A pie graph is more effective that other types of graphs for showing shares of a total.
