Example
Spreadsheet Format
Tree data structures are hierarchical. Each node has a parent nodes. In the example below, "Pet" is the parent of "Cat," "Dog," and "Rabbit". "Cat" is the parent of "Domestic Shorthair" and "Siamese." "Pet" is also the root note, since it has no parent.
Each row in the Tree Map data spreadsheet represents a node on the tree.
| Column 1 | Column 2 | Column 3 | Column 4 | |
|---|---|---|---|---|
| Data Type | plain text | plain text | number | number |
| Contents | The name of the node. | The name of the node's parent. Note:
| A value for the node. Note:
| A second value for the node. Note:
|
| Optional | x |
For the sample tree above, the first two columns might look like this:
| Node | Parent |
|---|---|
| Pet | |
| Cat | Pet |
| Dog | Pet |
| Rabbit | Pet |
| Domestic Shorthair | Cat |
| Siamese | Cat |
| Corgi | Dog |
| Great Dane | Dog |
| Labrador | Dog |
