How to start with Grafana Web Application?
Grafana web app shows a list of:
- Dashboards

- groups of dashboards that are displayed in a sequence
- they can be used to cycle dashboards on TVs without user control
- Snapshots
- interactive, publicly available, point-in-time representations of dashboards
- Library panels
- Reusable panels that can be added to multiple dashboards

In the right-hand side panel we can choose Visualisation type:
For example, Bar chart would look like this:
Suggestions tab show thumbnails for various visualisations:
