Creating a new treemap
                        You can create a new treemap on the sheet you are editing.
Do the following:
- From the panel to the left, drag an empty treemap to the sheet.
 - Click Add dimension and select a dimension or a field.
 - Click Add measure and select a measure or create a measure from a field.
 
You can add dimensions and a measure to the treemap in different ways:
| From one or more data fields. (The Fields section is not available in a published app.) | Creating a new visualization from fields | 
| From master items. | Creating a new visualization using master items | 
| From the properties panel. | Adding a dimension | 
When you have created the treemap, you may want to adjust its appearance and other settings in the properties panel.
