Hartley Logistics shows monthly delivery cost per parcel for 24 months and wants managers to see the trend and seasonal pattern clearly. Which visualisation is most appropriate?

A line chart with months on the horizontal axis is most appropriate because it displays continuous change over time, making trend and seasonality easy to see. Pie charts show shares of a total at one point, and tables or meaningless scatter plots obscure the pattern.

  2. BA pie chart with one slice per month
  3. CA scatter plot of cost against parcel colour
  4. DA table of unsorted monthly figures in small font

Explanation

Line charts show change over time and make trends and seasonality visible. A pie chart suits parts of a whole at one point in time, not 24 periods. Scatter plot against colour has no meaningful numeric relationship, and an unsorted table hides the pattern.
