Is there any node to write a Python Script to output visualization?

Hi @mlauber71 @HansS,

Thank you so much for sharing this. I actually got it working for basic things.
However, when I was trying to build a histogram, I’m able to see it when I execute the script and click ‘Show Image’, but I entirely different image when I execute the node and view the Output image. I think I’m making some mistake while saving it in the buffer.

I tried using StringIO from io package but then I get ‘No Image generated’.

‘Show Image’ output:

Knime-image
Knime-image920×529 24.1 KB

Node- Output Image:

knime-image1
knime-image1617×508 5.92 KB

Regards,
Vipul
