Knowing why we do what we do is important. Stephen Few lists four reason for creating Tables & Graphs in his book “Show me the number”. I really liked them so I am posting it here for your reference:

  1. it helps us communicate. It helps present information to others.
  2. it helps us analyze data. it helps us find the insights in the data.
  3. It helps us Monitor Performance. It helps us keep track information about performance e.g. Sales Performance, Speed of Manufacturing, etc.
  4. It helps us Plan. It helps us predict and prepare for the future.
