When you first access the Investor Map, the Items view mode is selected by default. If you choose to view a portfolio of items, its included items are displayed in as bubbles. If you choose to view a portfolio of portfolios in the Item mode, all items included in the entire hierarchy of the selected portfolio are displayed as bubbles. If you choose the `Portfolio mode', only the first level portfolios included in the selected portfolio are displayed. These portfolios will not be shown as bubbles, but as folder icons.
