Cannot see what it is contained in the clusters.
I am trying to learn the k-means operator. Once the process is executed I see the cluster bubbles in the Graph pane and the clusters folders in the folder view pane. When I click on one of the items to see what was inlcuded inside I, often, get a warning message: "No visualization available for object id". is it normal? maybe it depends on how dataset is composed? thanks for helping.
