### Dummy Tree Construction

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Construct a sample n-ary tree with nested children to demonstrate tree visualization. This example shows how to populate the node structure.

```python
root = NTreeNode('Lorem ipsum dolor sit amet')
root.children = [NTreeNode('consectetur adipiscing elit.'), NTreeNode('Etiam laoreet congue')]
root.children[0].children = [NTreeNode('Pellentesque finibus metus eget'), NTreeNode('ante aliquet ullamcorper')]
root.children[1].children = [NTreeNode('Morbi porta, diam at imperdiet venenatis'),  NTreeNode('neque eros bibendum tortor, quis')]
```

--------------------------------

### Generate and Print Tree

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Use `make_and_print_tree` to generate an ASCII representation of a tree structure. This function requires the root node, a function to get the node's value, and a function to get the node's children.

```python
from ascii_tree import make_and_print_tree
make_and_print_tree(root, get_value, get_children)
```

--------------------------------

### Value Extraction Function

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Define a function to extract the value from a node. This function is used by the Ascii Tree library to get the displayable content of each node.

```python
def get_value(node):
    return node.value
```

--------------------------------

### Update Charset and Generate Tree

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Sets the character set to 'ascii' and then generates and prints an ASCII tree. This is useful for basic tree visualization with ASCII characters.

```python
>>> update_param('charset', 'ascii')
>>> make_and_print_tree(root, lambda n: n.val, lambda n: n.children)
```

--------------------------------

### Update Screen Width Parameter in AsciiTree

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Use `update_param` to change the `screen_width` for tree rendering. This affects the maximum character width assumed by the tree.

```python
>>> from ascii_tree import update_param
>>> update_param('screen_width', 120)
>>> make_and_print_tree(root, get_value, get_children)
```

--------------------------------

### N-ary Tree Node Definition

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Define a basic n-ary tree node class with a value and a list of children. This is a prerequisite for constructing trees to be visualized.

```python
class NTreeNode:
   def __init__(self, val):
       self.val = val
       self.children = []
```

--------------------------------

### Children Extraction Function

Source: https://github.com/spandanb/asciitree/blob/master/README.md

Define a function to retrieve the children of a node. This function is essential for the Ascii Tree library to traverse the tree structure.

```python
def get_children(node):
    return node.children
```
