     Bubble map: Uses circles (bubbles) to show data on a map. The size of the bubble shows the
                         amount of something.

                           Example: Showing population size across different cities.
                         Bubble maps help you:

                          Compare proportions across different areas.

                          Visualise data geographically.
                          Show relative sizes.

                                                                       SPORTS SURVEY                  Skills
                                    A survey was conducted with 19 students in the
                                  class to find out their favourite sports. The results
                             were then visualised  in a pie  chart. Each section  of
                        the chart represents a different sport and the size of each
                        section shows how many students chose that sport as their
                        favourite.

                        Based on the pie chart, Answer the following question:

                        1.   Which sport should the teacher choose for the sports day based on the survey?

                        2.   How might focusing on the top two sports affect students who prefer other sports?
