The best type of graph to show quantities often depends on the nature of the data. For comparing discrete categories, a bar graph is effective, while a line graph is ideal for displaying trends over time. If you want to illustrate parts of a whole, a pie chart can be useful. Ultimately, the choice should focus on clarity and the message you want to convey.

I would argue that the best graph would be the bar graph, and if you can get it to be labeled with the numbers, then that's even better. Quantities of what, though? It depends on what information you're trying to present. If it's finances and this is a professional (I'm only assuming) setting, then I probably would choose either a pie chart or a scatter plot (pref. with lines connecting each drop or rise in the visual)...it's up to you, though. Which works best for what you're trying to convey?
