I think it would be nice to have an “Example Data Creator” node. In its configuration the user could toggle between various areas, such as “Life Sciences, Commercial, Pharmaceutical, Sociological, Geographical” data tables. Further configuration could allow the user to define the number of rows, clusters, correlations, noise, error rate, etc.
I think this would be great for users who are trying out Knime for the first time, or even experienced users who quickly need some data to play around with in order to test something.
It might also be convenient for users who need some example data for posting an issue on the Knime forum…!
