Types of Graphs and when to use them

After collecting data multiple times, it's helpful to create a graph—but what type of graph should you use?"

Here a chart that summarizes the different types of graphs and when to use them.

A bar graph is helpful to use when you have categories. 

Here is an example, notice the categories.

A circle graph is good for comparing parts to the whole.

A double bar graph is great for comparing sets of data, but not great for items involving time.

A box-and-whisker plot is useful for showing measures of variation. For example, if you create one for the ages of runners in a race, you can quickly see the overall age range, including the youngest and oldest runners.

A histogram is great at showing frequency of data in intervals.

Here is an example. 

A line graph is great at showing change over time.
