Cross-platform data visualization best practices using power BI and Tableau

As organizations strive to democratize data and scale insight across various departments, data visualization tools like power BI and Tableau are becoming organizational intelligence strategies. The study presented in this review explores the best practices of designing, delivering, and administering the visualizations on these two favored platforms, based on usability, visual consistency, accessibility and governance. Using comparative literature, theoretical models and experimental results of the subject, the article proposes a Unified Visualization Effectiveness Framework (UVEF) as a way to support cross-platform excellence. The paper has discovered that each of the platforms has its own strengths however, the strategic alignment, visual literacy, and standardization are crucial elements of successful implementation, not the tools used. The paper concludes by giving future recommendation suggestions, which include the need of intelligent-supported design, blended visual control, and migration to cognitive-friendly user interfaces in hybrid analytics systems.
