Expressing Data in Charts/Graphs

        In representing data, we may not fully understand if the data is expressed in numbers or tables.  We may not know the difference between them or we can't easily differentiate the things we are expressing in Excel.

        Thus, in expressing one's data, we can easily understand if it is expressed in a chart or a graph.  Charts or graphs are commonly used, for example, in representing a company's sale from last year to this year.  We may automatically understand the data being shown if the data is represented in charts.  We may conclude that the sale of the company increased because of the chart.
