v0.13.0 - 2023-12-04

This release makes significant improvements to the Diagnostic Reports! The report now runs a diagnostic to calculate scores for three basic but important properties of your data: data validity, data structure and in the multi table case, relationship validity. Data validity checks that the columns of your data are valid (eg. correct range or values). Data structure makes sure the synthetic data has the correct columns. Relationship validity checks to make sure key references are correct and the cardinality is within ranges seen in the real data. These changes are meant to make the DiagnosticReport a quick way for you to see if there are any major problems with your synthetic data.

Additionally, some general improvements were made and bugs were resolved. The LogisticDetection and SVCDetection metrics were fixed to only use boolean, categorical, datetime and numeric columns in their calculations. A bug that prevented visualizations from displaying on Jupyter notebooks was patched. The cardinality property in the multi table QualityReport can now handle multiple foreign keys to the same parent. Finally, a new visualization was added for sequential/timeseries data called get_column_line_plot.
