How do I troubleshoot data model relationships that are causing incorrect visualizations in Power BI?

When the visual representations in Power BI generate results that are not as anticipated, resolving the issues concerning the relationships existing within the data models becomes paramount. This query explores the common relationship issues that may occur - wrong cardinality, too many relationships, or relationships that cross over themselves - that may result in erroneous computations or misleading graphical representations. The purpose of this note is to learn how to resolve these problems by altering relationships in the model, employing such features as the “Manage Relationships” window, and conducting the model in practice with smaller graphics or cutouts in order to locate and resolve the issue.
