2. Try at least three different graph or chart types before deciding which one illustrates the information best. State why this is the case. Those who work with numbers a great deal acknowledge that pages of figures and calculations do not always illustrate the points well and therefore these comparisons are illustrated by graphs or charts to better show results. Charts or graphs that could be used include bar charts, pie charts, line graphs, doughnuts, scatter graphs and so on. Excel spreadsheets can produce such charts or graphs very quickly once the figures are put in.
