How to find feature importance after model building?

After doing model building, how can we find the feature importance? The most important features predicted by model.

@somnathdas76 some model would just provide you with the feature importance (most models, Random Forest, XGBoost …), but you can also explore the Global Feature Importance – KNIME Hub

I tried my hand at one idea mentioned here to re-engineer the feature importance via Tree models and the likes. But I am not 100% satisfied with the results:

Then … @Morris_Kurz has provided us with two interesting nodes that also might help (,
