US Patent 11921979 Data preparation user interface with configurable process flow elements

A computer system concurrently displays a plurality of panes in a user interface. The panes include a first pane that displays a flow diagram having one or more nodes. Each node contains one or more icons. Each icon represents a respective data transformation operation. The panes include a second pane that displays a plurality of data rows and/or data columns for an intermediate dataset corresponding to a user-selected node. The computer system receives a user input, in the first pane, to perform a first data transformation operation at a selected node. In response to receiving the user input, the computer system performs the first data transformation operation. The computer system displays, in the first pane, an additional icon corresponding to the first data transformation operation at the selected node. The computer system updates the second pane in accordance with the first data transformation operation.
