How to make bar graph

I have attached a spreadsheet as an example. I am trying to figure out how to put my data on a bar graph. I know how to do when its a more simple one. But take a look at this one. Basically I have multiple donors. There are three levels of donation, Gold, Silver and Bronze. They donate money each race. How do i put this data on one bar graph? I also want to make sure the donors are the same color throughout the whole thing. Any ideas? Does this make sense?
