If you can illustrate numerical information in a pictorial form then that is a graph. So there are infinitely many kinds of graphs. One of my favourites illustrates Napoleon's invasion of Russia and his retreat. See link for more.
There are probably more kinds of graphs than most people can imagine. A graph is simply a means of conveying information in a visual manner.
Some interesting but unusual graphs are:
Florence Nightingale's study of Crimean mortality. She was one of the early statisticians to grasp the power of graphs.
Napoleon's invasion of Russia.

Bar graphs and line graphs.
The answer depends on what information is graphed. There are distance-time graphs, velocity-time graphs, speed-time graphs, acceleration-time graphs.
Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.
There are an unlimited number of graphs that can be mathematically created.

Linear and Exponetional.
Many kinds of information can be shown on maps and graphs. Geography, population, pronunciation differences, income, age, religion... almost anything.

Smart Art is provides the facility to create a variety of charts, like organisational charts, flow charts etc. These charts are specialised, and customisable. So it is usually specialist users that will use a lot of them, though anyone can use them.

Some common types of graphs used in science include line graphs to show trends over time, bar graphs to compare different categories, scatter plots to display relationships between variables, and pie charts to represent parts of a whole. Choosing the appropriate graph depends on the data being presented and the message that needs to be conveyed.
they give us information about anything which we want to compare.
