Reality Check The graphical display in contrast to the tabular presentation is associated with the visual system. It is easy to remember and retrieve complex information with graphs. Therefore, graphs are increasingly used to communicate the data. There are various types of charts that are available in the literature. However, pie chart, bar chart, and line chart are the most frequently used graphs. The digital ecosystem along with raging COVID-19 pandemic has further accelerated the data flow through a graphical display. However, due to clutter, many visual displays are unclear and inefficient for effective communication. Therefore, it is critical to know the fundamental of the graphical display. In this regard, the researcher has a few questions: • Are there general rules for graphical display? • Are there specific rules to make an effective pie chart? • Are there specific rules to make an effective bar chart? • Are there specific rules to make an effective line chart?
