Data Visualization in PostgreSQL With Apache Superset

Data visualization tools like Apache Superset and Metabase help analysts and stakeholders understand complex data quickly by transforming it into graphical representations such as charts and graphs. These tools allow users to identify trends, outliers, and patterns, leading to informed decisions and insights. While paid options like QlikView, Power BI, and Tableau offer wider feature sets, better scalability, and more support, open-source tools like Apache Superset are free to use and modify but may require technical expertise and have limitations for large deployments. In this article, we demonstrate how to visualize data using Apache Superset with PostgreSQL by creating a dataset, visualization, and dashboard. We also discuss best practices for data visualization and provide an FAQ section for common issues.
