    Using Charts for Data Representation

                      Charts are a way of representing data visually, making it easier to understand and compare.
                      Instead of reading long lists of numbers in a table, charts use shapes like bars, lines and slices to
                      tell the "story" of the data instantly.

                      Charts plot data on coordinate axes, where the X-axis represents categories and the Y-axis
                      shows values. By turning data into a visual format, charts help us see patterns and trends
                      quickly.

                      A chart has different parts that work together to display data clearly. The main components of
                      charts are as follows:
                        Chart Area: This is the whole space that holds the chart, including everything like the title,
                         axes and data.

                        Chart Title: The title tells you what the chart is about, so you know what data it is showing.

                        X-axis: The horizontal line (left to right) that shows the categories or groups of data.
                        Y-axis: The vertical line (up and down) that shows the values or measurements of the data.

                        Plot Area: The space where the data is shown, excluding labels and the title.

                        Data Series: The actual data points shown on the chart. These are represented by bars, lines
                         or dots.
                        Data Labels: The numbers shown next to the data points to tell you the exact value.

                        Gridlines: The horizontal and vertical lines that help you read the values easily by dividing the
                         chart into sections.

                        Legend: The part that shows what each colour or symbol means in the chart.
