Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.
numbers
Some data.
all of the graphs
Bar graphs and line graphs.
All graphs are graphical graphs because if they were not graphical graphs they would not be graphs!
Title Axes Data Labels Series Names
Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.
data
they all compare different amounts

All graphs need labels or data on both of the axis to be of use. So all graphs require a "key"
No.

graphs measure how far something can go and the distance between. that's all I got right now
