As mentioned with each of the preceding charts that we have seen, it is important to understand what type of data you have. If you have continuous variables, then a histogram would be a good choice. Similarly, if you want to show ranking, an ordered bar chart would be a good choice.

Choose the chart that effectively conveys the right and relevant meaning of the data without actually distorting the facts.

Simplicity is best. It is considered better to draw a simple chart that is comprehensible than to draw sophisticated ones that require several reports and texts in order to understand them.

Choose a diagram that does not overload the audience with information. Our purpose should be to illustrate abstract information in a clear way.
