                                                                show the changes in data over a period of time
                                                                or  for  comparison  among  the  different  data

            Pie Chart: It is a circular chart divided into sectors where
            each sector shows the relative size of each value. It always
            shows only one data series. It is useful when you want to put

            emphasis on a significant element.

                                                              These  bars  can  be  placed  horizontally  on  the
                                                              chart area. It illustrates the comparisons among
                                                              the individual items. In this chart, categories are
                                                              represented  on  the  vertical  axis  and  values  are
                                                              represented on the horizontal axis.









            Area Chart: It is used to display the quantitative
            magnitude of the data graphically. These charts
            are based on the features of the line chart. They
            basically  emphasise  the  area  between  the  line
            and the axis with the help of the colours, textures,
            pictures, etc.
