Read this article 16 Captivating Data Visualization Examples and find out how you can visualise your data in different ways.
Important data needs distinct graphical elements
Not all numbers are made equal, so tell the most important story with the dominant graphical elements. Use things like size, shape, position and rotation for important data. Less significant attributes can be communicated by things like colour, transparency or tone.
Show greater numerical quantities by distinct graphical elements
The bigger the number gets, the bigger the bar gets, or the higher the line. Also, try not to use these elements for something else: if you’re visualising world population data, don’t group countries by size.
Check out how Gapminder does this with colour in their visualisation showing the Wealth & Health of Nations.
Use standardised systems when possible
Symbols that are commonly recognised, such as currencies, transport signs and warning symbols, are standard across the world. Where possible make use of the symbols that are universally understood.
