A time series graph would be the best choice for showing how rainfall changes over time, in this case over the course of a year. This type of graph plots data points on a timeline, allowing for easy visualization of trends and patterns over time. A pie graph would not be appropriate because it is used for showing parts of a whole, whereas rainfall amounts are not part of a whole. A pictograph could be used, but it would not show changes over time as clearly as a time series graph. A Pareto chart is used to show the relative frequency or size of problems or defects, not rainfall data.
