<h3>What is Annual Rainfall Graph?</h3>
This refers to the climatic graph which is used to show the average rainfall which is recorded for a particular rainfall in a given time frame.
With this in mind, we can see that this can be represented on a line graph or on a bar graph and the data are recorded on the same axes.
Please note that your question is incomplete so I gave you a general overview to get a better understanding of the concept.
