 ## Dashboards, Panels, the building blocks of Grafana...
 
-Dashboards are at the core of what Grafana is all about. Dashboards are composed of individual Panels arranged on a grid. Grafana ships with a variety of Panels. Grafana makes it easy to construct the right queries, and customize the display properties so that you can create the perfect Dashboard for your need. Each Panel can interact with data from any configured Grafana Data Source (currently InfluxDB, Graphite, OpenTSDB, Prometheus and Cloudwatch). The [Basic Concepts](/guides/basic_concepts) guide explores these key ideas in detail.
