+  An exported JSON representation of a Grafana dashboard designed to visualize weather data. This dashboard includes a set of pre-defined panels and widgets that display various weather metrics. Additionally, within this dashboard configuration, there are advanced time-series analysis queries. These queries are tailored to fetch, aggregate, interpolate, and process weather data over time.

+  To ensure the dashboard functions correctly, it's necessary to configure the data source within Grafana. This dashboard uses the `grafana-postgresql-datasource` or another configured default data source. In the data source settings, fill in the necessary parameters to connect to your CrateDB instance. This includes setting up the database name (`database=doc`), user, password, and host.
