Solution
Answer :
we can have different type of graphs :
Bar graph : A bar graph can be horizontal or vertical. Each axis is labelled with either a categorical or a numerical variable.
Pie graph : Pie charts represent the parts of a whole. Each ‘section’ or ‘slice of the pie is a data percentage.
Pictograph : In pictographs, smaller picture represents a certain amount of an item and the pictures in the graphs are stacked up one after another.
Line Graphs : Used to display comparisons between 2 variables, line graphs involve an x-axis horizontally and a y - axis vertically on a grid.
