@EsIstJosh I've tried installing your fork, but it'm experiencing the following issue:

Traceback (most recent call last):
  File "C:\...\visualize.py", line 42, in <module>
    chart = Chart()
            ^^^^^^^
  File "C:\...\venv_trading_2\Lib\site-packages\lightweight_charts\chart.py", line 185, in __init__
    super().__init__(window, inner_width, inner_height, scale_candles_only, toolbox, position=position)
  File "C:\...\venv_trading_2\Lib\site-packages\lightweight_charts\abstract.py", line 1087, in __init__
    from lightweight_charts_.polygon import PolygonAPI
ModuleNotFoundError: No module named 'lightweight_charts_'

I've installed it using the following command with Python 3.11.4:
pip install -U git+https://github.com/EsIstJosh/lightweight-charts-python
Maybe I'm not doing it right. But if you could help in any way, that would be great.

I think it has to do with me having an underscore after this : ModuleNotFoundError: No module named 'lightweight_charts_',

In my setup I have the project in my working directory so I could just reference it like that but it should probably be renamed back.

Alright I'll make a local edit until you've changed it in the repo. Thanks for the reply!
Edit:
For anyone interested, changing from:

from lightweight_charts_.polygon import PolygonAPI

To

from .polygon import PolygonAPI

Fixed it.
