LINE CHART
                  A  line chart is a type of graph that displays

                  continuous data at regular intervals. It is
                  generally used to highlight the changes that
                  take place in a value through a specified period
                  of time. It is also known as a frequency polygon.

                                                                      An  area  chart displays the quantitative
                                                                      magnitude of the data graphically over the
                                                                      course of time. It also depicts the relationship

                                                                      of parts to a whole by displaying the sum of
                                                                      plotted values. The area chart emphasises the
                                                                      area between the line and the axis with the
                                                                      help of the colours, textures, hatchings, etc.

                                                                      line chart.



                  PIE CHART
                  A pie chart is shaped like a circle divided into

                  slices, each slice showing the relative size of
                  each value. The pie chart only displays one data
                  series in the form of comparative charts. It is
                  useful when you want to emphasise a significant
                  element.

                                                                       A scatter chart is also known as XY scatter
                                                                       plot chart. It shows the correlations between
                                                                       the two sets of values. The X and Y axes are
