US Patent 11593324 Reversible data transforms

In an example, a method to generate a visualization of data from a data source based on a contract includes applying a first reversible transform to data of a data source to generate a first intermediate data structure without modifying the data of the data source. The method includes applying a second reversible transform to the first intermediate data structure to generate a second intermediate data structure without modifying the data of the data source. At least one of the first intermediate data structure or the second intermediate data structure is in a format suitable to satisfy a contract. The method includes displaying a visualization of the data of the data source based on the contract satisfied by one or both of the first intermediate data structure or the second intermediate data structure. The displayed visualization has a visualization type specified by the contract.
