Power BI's standard visuals offer limited customization, which can frustrate clients needing highly tailored dashboards for branding or unique functionality. Power BI consultant must rely on third-party custom visuals or develop bespoke visuals using Power BI's Developer Tools, requiring advanced coding skills and additional effort. This dependency can lead to higher project costs and potential compatibility issues during Power BI updates. Consultants must carefully evaluate whether the benefits of custom visuals justify the resources required, often recommending a mix of standard and customized solutions to balance usability, aesthetics, and project constraints.
