I have had great experiences using Rapidminer community edition which is like this but on steroids. I say community edition because they've started charging for the pro versions and probably future versions so community is still free and open source. I think a lot of people miss out by not using these tools to prototype their pipelines. You can get probably an order of magnitude more experimentation done using one of these visual pipeline creators vs. trying to essentially reinvent the experiment infrastructure yourself in your own code. https://en.m.wikipedia.org/wiki/RapidMiner https://en.m.wikipedia.org/wiki/RapidMiner
