Nowadays, dashboards are everywhere. We use them to monitor our stocks, to see our store sales, to look at real-time visitors of our website, and for many other tasks. Dashboards are commonly included in many software and services that we use every day. Designing a dashboard is a simple job, after all. By using tools such as Power BI, you can easily arrange your data on the screen just by dragging visual elements, and then share them with colleagues or embed them online. The complex part is not related the technical aspect of the job, which is easy. The difficult part are the conceptual rules of a smart and effective design that make your dashboards easy to use and pretty to see.
