1. A computer-implemented method comprising: providing an engine in communication with a re-written query plan and with an interface, the re-written query plan resulting from application of a query plan re-write rule to a previous query plan; causing an engine to reference the re-written query plan in order to generate a visualization comprising a graph including an operation node and a table node; and causing the engine to communicate the visualization to the interface for display in a dashboard, wherein the dashboard further includes a change log separate from the graph and reflecting changes to the re-written query plan in a format comprising an identifier of the operation node, an operation type, an updated parent node identifier, and an identifier of the query plan re-write rule.
