The definition provided matches that of histograms, which use bars or rectangles to display data intervals and corresponding frequencies. Scattergrams are used to display data that may have a relationship between two variables. Frequency polygons use lines to connect midpoints of bars in a histogram. Ogive curves use lines to connect cumulative frequencies. Bar graphs are similar to histograms but do not necessarily have continuous data intervals.
