For decades, data visualization was the guarded domain of BI specialists, statisticians, and data analysts. If an executive wanted a dashboard or a policymaker needed an analysis, they had to request it through a central analytics team and wait days or weeks for results. That world is gone. Today, thanks to platforms like Tableau, Power BI, and open-source frameworks such as Plotly Dash and Plotly Studio, almost anyone can spin up an interactive dashboard. This shift, known as the democratization of data visualization, promises faster insights, broader participation, and fewer bottlenecks from overworked data teams or gaps in expertise.
