We can visualize how much nations in a particular geographical region import from other regions in a different way, using partition diagrams called TreeMaps. We will create a filter to select records for Asian (excluding Near East) nations. The first partitions will be proportional to the total import trade volume of each Asian nation. Then, each nation's partition will be further partitioned to show how much and in what proportions the nation imports from different geographical regions.
The nations controlling the largest area in the first partition will be the nations dominating the import market in Asia (excluding the Near East). The larger partitions inside each nation will represent the export market that supplies most of the merchandise goods to the corresponding Asian nation:
