  • Tell a story and makes it easier to grasp
  • Represent large quantity of data coherently
  • Assist readers to discern the relationship of the data
  • Enable discovery of new insights

Types of data visualization

1. Time series data

This type of data visualization is typically in chronological form. It involves temporal measurements (changes over time). Line chart is typically used. However, you can also use a bar chart or heat chart to represent time series data.

Examples

A simple line chart that indicates the change over time.

3. Compare sets of values

When showing comparison data like highest or lowest value, use bar chart or histogram. You can also use tree map or bubble chart for comparison of more than two elements.

Examples

Simple comparison between two elements over a period of time.

4. Percentage values

To indicate percentage, use a pie chart. There are multiple creative variations of a pie chart. However, do not overuse pie charts. It may make your data. Do not use more than 5 to 7 fields of data as it will look overcrowded. Thus, it defeats the purpose of clear data representation. Use a pie chart when all the elements do not overlap and provide a complete picture.

Examples

A simple pie chart that provides a complete story.
