Q.Write a short note on: Simple bar diagram

A simple bar diagram is a one-dimensional diagram of bars of equal width placed on a common base, whose lengths are proportional to the values they represent. It is used to present a single series of data, such as one variable over time or across categories. ## Meaning A simple bar diagram is a one-dimensional diagram used to represent a single set (series) of data. It consists of a number of bars (rectangles) of equal width, drawn vertically (or horizontally) on a common base line, with equal gaps between them. Key features are: - the width of all bars is kept equal; - only the length (height) of each bar varies, and it is drawn in proportion to the value it represents; - the bars are usually arranged in the order of the data (for example, year-wise). For example, the production of a crop in five different years can be shown by five bars of equal width whose heights are proportional to the output in each year. A simple bar diagram is easy to draw and understand and makes comparison of the values clear at a gla …
