Preprocessing in Synapse gives you a ridiculous amount of power to visualize and transform your data. Visualizers can be connected chains for unlimited drill down data mining. Non-destructive filtering allows you to modify and transform your data. Selections allow you to pick out interesting subsets of your data - either through a powerful query language or by visual selection (or both). Do you find yourself missing writing code? No problem - there's a filter for that! Enjoy the journaling function that creates automatic documentation for your filters, selections and graphs. It even documents automatically what you did to get a certain graph.
