What are Dashboards in Salesforce?

Hello,

A dashboard is the graphical representation of the data generated by a report (or multiple reports) at certain point in time. So it's a snapshot of data, to obtain the latest data you need to refresh them either manually or in a scheduled manner.

Thanks.

Charts, tables, gauges, metrics are component in the dashboard. User can select any of these components to view data.
Chart: Chart is used for graphical presentation of data. The Visualforce has a variety of chart types to represent your data.

Gauge: This can be used when the single value needs to point within the range of custom values.
Metric: This used to represent data based on one key value.
Table: Table is used to show the set of data.
