Hi Shuchi!
Line graph and pie chart are being drawn to represent data
diagrammatically for various purposes
If the presentation is to highlight various data as a percent
of the total data, then a pie graph is ideal Let say if you want to
draw the pie chart of the given data, then you need to find the
angles of the sectors representing the cost of the cars in
different years You can calculate this by considering the sum of
the cost of the car in different years as 360°
This (the sum of the cost of cars in various years) is of no sense
That is why drawing the pie chart of the given data is of no sense
However the given data provided by you is a case of continuous data
distribution In this case a line graph is suitable
