Data-Handling

Graphs and Charts

Graphs and charts display data in a visually arresting way, that is much easier to understand and interpret than a table of numbers.

Presenting data in a graph or chart can illustrate a comparison, relationship, or trend.

Some common graph types are:

• Bar chart
  
• Pie charts
• Scatter diagram
• Line graph
  
• Venn diagram
