treegraph chart type not working #12
Description
I've got a treegraph chart (simplified), which I tested in JSFiddle and then adapted for python:
def my_chart():
data = [
{"id": "step-1", "name": "Step 1", "color": "red"},
{"id": "step-2", "name": "Step 2", "parent": "ingestion", "color": "grey"},
]
return ui.highchart(
{
"title": {"text": ""},
"series": [
{
"type": "treegraph",
"data": data,
"tooltip": {"pointFormat": "{point.name}"},
"marker": {"symbol": "rect", "width": "25%"},
"borderRadius": 5,
"dataLabels": {
"pointFormat": "{point.name}",
"style": {"whiteSpace": "nowrap"},
},
}
],
}
)When I load a NiceGUI application with this chart embedded, I am getting the follow error (in the browser console, NiceGUI itself seems happy enough):
vue.global.prod.js:5 Error: Highcharts error #17: www.highcharts.com/errors/17/?missingModuleFor=treegraph

I take this to mean that the vue library for treegraph is not loaded. However, I can find the path .venv/lib/python3.11/site-packages/nicegui_highcharts/lib/highcharts/modules/treegraph.js and since the Highchart class itself is initialised with the following, I was expecting this to work:
dependencies=[
'lib/highcharts/*.js',
'lib/highcharts/modules/*.js',
]And indeed, I can find the following entry in ui.highchart.exposed_libraries:
Library(key='36fb47e853cb0c7e42f708da1527b47e/treegraph.js', name='treegraph', path=PosixPath('/Users/elias/dev/hackathon-lumberjacks/.venv/lib/python3.11/site-packages/nicegui_highcharts/lib/highcharts/modules/treegraph.js'), expose=True)
So I'm a bit lost as to why I am getting the issue.
Just to confirm, if I change the graph type to e.g. line, it does render. Obviously, the series isn't compatible, but I then at least see the axes rendered.
