Data Visualisation Technique 3

             Name of the Representation                                 Line Graphs
             Description                    It is a graph that uses lines to connect individual data points. A line graph
                                            displays quantitative values over a specified time interval.

             Suitable for which type of data? It is most suitable for continuous data to identify a trend or pattern in your
                                            data. For example, changing fuel price, daily profit earned by a shopkeeper,
                                            etc.

             Name of the Representation                                Scatter Plots

             Description                    Graphs  that  present  relationships between  two variables in a  dataset.
                                            Independent variables are plotted on the X-axis, while dependent variables
                                            are plotted on the Y-axis.

             Suitable for which type of data? It is used to compare 2 data sets in the same environment of Independent
                                            and Dependent Variables.

                                            Example: rise in fuel prices in different countries over the period of time
                                            and per capita income in the same period, population size over the period
                                            of time in cities or countries and the disposable income during that period.
