the data for two years.
(b) Pie chart for percent of Australian exports
2

(c) Certain interesting conclusions can be made in relation to the visual summary of the given
export data from part(a) and part(b). These are listed below.
 The market share of China in Australian exports has made rapid strides
considering that in 2004-2005, it stood at a modest 15% while in 2014-2015, it
jumped to 40%. This increase in the market share implies that all the other
nations have lost shares in the given period.
 The absolute exports from Australia to all the countries listed above have shown a
rise in absolute terms with the noticeable exception of United Kingdom. This
would indicate that exports from Australia to UK have seen a decline during the
given period in absolute terms.
 It would be expected that exports should be higher to neighbouring countries
owing to lower transportation cost and hence high competitiveness. This is not
supported by the exports from Australia to New Zealand which as indicated from
column chart in part (a) highlight that no growth has occurred overa decade.
