2.4.1 Charts
i. Line Chart
A line chart is used to illustrate the dependence or relationship
between two variables. It assists us in recognising patterns, trends,
and fluctuations within your data. It can also be used to compare
variations over time. Figure 2.1 shows an example of line chart for
the trend of product sales by month.

ii. Pie Chart
Most frequently, a pie chart is used to compare the components of a
whole. It is most effective when a limited number of components and
percentages are used to describe the content. Using a pie chart, you
can readily compare which products are the most commonly used,
such as in Figure 2.2, which depicts the most popular social media
platform among users.
