Generated html is blank

[NguyenTuan-Dat]

I'm tried follow the tutorial but output is blank like this image.

This is my code, can you help me check my mistake?

from treeplotter.tree import Node, Tree, ConnectorStyle, NodeStyle, create_tree_diagram
root = Node(name="root")
arrow_connector = ConnectorStyle(
    arrow_end="classic",  # these come from the Raphaël documentation.
    arrow_width="wide",
    arrow_length="long")
node_style = NodeStyle(
    background_color="#89ADF0",
    border_radius="10px")
root_child = []
for node in tree:
    parent_node = Node(name=some_name, image=img_path)
    childs = []
    childrens_node = tree[node].get_childrens()
    for child in childrens_node:
        child_node = Node(name=some_name, image=img_path)
        childs.append(child_node)
    parent_node.add_children(childs)
    root_child.append(parent_node)
root.add_children(root_child)
print(root.num_children)
connected_tree = Tree(root=root, connector_type="step", connector_style=arrow_connector, orientation="west",
                      node_style=node_style)
create_tree_diagram(tree=connected_tree,
                    save_path="/Users/ntdat/Downloads/tree",
                    background_color="#cf2b2b",
                    webshot=True,
                    verbose=True)

Thanks for filing this issue @NguyenTuan-Dat ! I will take a look at this today and get back to you ASAP.

Thanks again for filing @NguyenTuan-Dat ! I need a bit more info for the following before I can debug:

• It looks like you're defining a tree somewhere outside of the above snippet (see for node in tree). I can't run the snippet without seeing how tree is defined.
• I think you added some methods to Tree (get_childrens, tree indexing tree[node]). This is really cool, and please feel free to submit a Pull Request with these contributions! I can't run the snippet without these methods.

Could you send a minimal reproducible example with your issue? (Also: it looks from the above image that you're previewing your .html file with the spacebar –– as far as I know, the tree image cannot be rendered from preview; it'll only be visible if you open the file in the browser.)

Hi, my html is also blank.
Here is the code I used (basically same as the tutorial)

from treeplotter.tree import Node, Tree
root = Node(value=1.0, name=None)

child1 = Node(value=0.5, name=None)
child2 = Node(value=1.0, name=None)
child3 = Node(value=3.0, name="A")
root.children = {child1, child2, child3}
root.children

granchild1 = Node(value=0.5, name=None)
granchild2 = Node(value=3.0, name="B")
granchild3 = Node(value=2.0, name="C")
greatgrandchild = Node(value=1.0, name="D")

child1.add_children([granchild1, granchild2])
child2.add_child(granchild3)
granchild1.add_child(greatgrandchild)


tree = Tree(root=root)

from treeplotter.plotter import create_tree_diagram
create_tree_diagram(
    tree=tree,
    save_path="C:\Eszter\stuff",
    webshot=True,
    verbose=True
)

I am attaching the output files:

Thank you for your help on this

Running the same code as @celeszter , I'm getting blank HTML as well, and the following JS error:
