Hello Forum!
As I mentioned in a previous topic, I’m learning how to make plots/charts with Matplotlib in Python, so I’m sharing what I have created in case the workflows are useful to other KNIMErs 
This time I’m sharing an Annotated Heatmap generated using the -Python View- node and a series of selection widgets to select colours and labels.
You can find my workflow on the hub:
I hope this is useful
Thanks
Heather
