a bar graph or line plot
Error bars are often used on graphs to show statistical comparisons.
Every graph shows comparisons of some kind or another.
You use a bar graph when you need to show comparisons between items. (categories)
A textual graph is a graph where the results and comparisons are written out instead of expressed in numbers. A textual graph has a list of comparisons divided into columns much like a pros and cons list.

a histrogram
A graph refers to a diagram that shows the relation between variable quantities. Bar graphs are often used to show statistical comparisons because they show the relevant data side by side.
A graph
Line graph
A bar graph and a graph with both bars and lines typically include statistical comparisons. Bar graphs are used to compare quantities across different categories, while line graphs can show trends over time. A pie chart, on the other hand, represents parts of a whole and is not ideal for comparisons. A data table can also provide comparisons but in a more numeric format rather than a visual one.
You would use a bar graph to show data changes over time or to show comparisons among items. A line graph can also be used to show data changes over time or comparisons. A pie/circle graph would be used to show the relative amount/size of items in a data set. A scatter plot is used to show trends and similarities in a large number of data points.
