Taskweaver as a library - responses with image

[AmaliMatharaarachchi]

I'm running taskweaver as a library inside a docker container.
I get following output

The plot has been successfully created using the points (1,2), (4,5), (6,8). However, it seems there was an issue displaying the plot. Please ensure your environment supports graphical output or try running the code in a local Python environment with graphical support.

what changes should I do to support it.

FYI, my docker image has following format.

FROM python:3.10-slim
...
RUN git clone --branch v0.0.1 --depth 1 https://github.com/microsoft/taskweaver.git
COPY taskweaver_config.json /app/taskweaver/project/taskweaver_config.json
RUN pip3 install -e /app/taskweaver
