+and understand your metrics no matter where they are stored.  Create, explore,
+and share dashboards with your team and foster a data-driven culture:
+@enumerate
+@ite Visualizations: Fast and flexible client side graphs with a multitude
+of options.  Panel plugins offer many different ways to visualize metrics
+and logs
+@item Dynamic Dashboards: Create dynamic & reusable dashboards with template
+variables that appear as dropdowns at the top of the dashboard.
+@item Explore Metrics: Explore your data through ad-hoc queries and dynamic
+drilldown.  Split view and compare different time ranges, queries and data
+sources side by side.
+@item Explore Logs: Experience the magic of switching from metrics to logs with
+preserved label filters. Quickly search through all your logs or streaming them
+live.
+@item Alerting: Visually define alert rules for your most important metrics.
+Grafana will continuously evaluate and send notifications to systems like Slack,
+PagerDuty, VictorOps, OpsGenie.
+@item Mixed Data Sources: Mix different data sources in the same graph! You can
+specify a data source on a per-query basis. This works for even custom
+datasources.
