A bar diagram of art forms in kerala

Answer 1

Answer:

As the name suggests, when data is presented in form of bars or rectangles, it is termed to be a bar diagram.

Features of a Bar

The rectangular box in a bar diagram is known as a bar. It represents the value of a variable.

These bars can be either vertically or horizontally arranged.

Bars are equidistant from each other.

Each bar originates from a common baseline or a common axis.

The width of bars remain same but the height changes, according to the value of a variable, to denote the difference between their values.

Unless they are in a specific order, the convention is that bars can be arranged in an ascending or descending order.
