                         Data is simply an organised collection of information, which can be facts, numbers,
                           or measurements.
                         Data helps us understand and make sense of information, allowing us to compare
                           things, identify patterns, and draw conclusions.

                         Using pictures or symbols to represent data, where each symbol represents a certain
                           number of items, is known as a pictograph.

                         Every pictograph must have the following: title: The title tells us what information the
                           pictograph gives. Key: The key tells us the meaning and the value of the picture or
                           symbol.

                         A representation of data with the help of bars (rectangles) in a diagram is called a
                           bar graph or bar chart.
