  1. Important Point to Remember

Data - Data is any piece of information that has been collected in a number, word, measure, symbol, or any other way. 

Type of Graph

  • Pictograph - When the data is represented by pictures or symbols, it is referred to as a Pictograph.
  • Bar Graph - In a bar graph, all the data is represented by equal width bars with equal gaps, but the bar height represents the respective values.

     2. Circle Graph or Pie Chart

If the data is represented in the form of a circle, then it is referred to as a pie chart. This graph illustrates the relationship between a whole and its parts. The circle must be divided into sectors. Each sector is related to its activity. It is used when we have information about a percentage or fraction.

  • Drawing pie charts

If the data is expressed as a percentage, then the corresponding angles need to be determined in order to show them on the pie chart. Since it is known that a full circle is composed of 360 degrees, the fraction of 360° must be calculated for each sector.
