    It is mainly used to compare different groups or items easily. Bar graphs can be drawn
                     either vertically or horizontally and they make information simple to understand at

                     a glance.
                     Let us understand the concept of bar graph with the help of an example.

                     In a class survey, students were asked about their favourite fruit:

                       Apple: 20 votes

                       Banana: 15 votes

                       Mango: 10 votes

                       Orange: 5 votes

                     In a bar graph, each fruit is shown as a separate bar. The taller the bar, the more
                     students like that fruit. This allows us to easily compare how many students prefer

                     each fruit.

                                                                    Votes

                         Orange

                          Mango

                         Banana

                           Apple

                                 0               5               10               15              20              25
                                                                        Votes

                     In the given graph, the horizontal line shows the fruits and the vertical line shows the
                     number of votes.

                     Line Graphs

                     A line graph shows data using points joined by lines. It is used to show changes over
                     time. Line graphs are great for understanding how data changes continuously, like

                     temperature or stock prices.
