### How are bar graphs useful in geography?

bar graphs aid geographical understanding as they enable simple
comparisons to be made and can be used to display a variety of data
such as populations. Also there are many different types of bar
graphs that can display different types of data. For example a
compound could be used to show the populations in different
countries in different years. Divergent bar graphs can also show
positive and negative data.

### What are 2 graphs that compare 2 sets of data?

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.
