Q. Illustrate diffrent types of graphs?
Circle graphs a circle graph is utilized to show the parts of a fixed whole. This kind of graph is occasionally called a pie chart because it is a circle divided into wedges that look like pieces of pie. Every wedge represents a percentage of the whole. The whole graph represents 100 percent.
Bar graphs A bar graph is frequently used to show how a quantity varies with location, time or temperature. In this circumstance the quantity being measured appears on the vertical axis. The independent variable time for instance appears on the horizontal axis.
