    There will be new Analyzer visualizations based on Weka algorithms (decision trees and k-means clustering) available via the marketplace in the forthcoming 6.1 release of the suite. Alternatively, you can use Weka to build a classifier or clusterer on some data and then use the WekaScoring PDI step to append predicted class labels/cluster assignments to data. Scored data can be written to a database for visualisation in reports and dashboards.

    Cheers,
    Mark.
