+Grafana 7.4 adds a beta version of the next-gen graph visualization. The new graph panel, the _Time series_ visualization, is high-performance visualization based on the uPlot library. This new graph visualization uses the new panel architecture introduced in Grafana 7.0 and integrates with field options, overrides, and transformations.
 
 The Time series beta panel implements the majority of the functionalities available in the current Graph panel. Our plan is to have close to full coverage of the features in Grafana 8.0, coming later this year.
 
 Apart from major performance improvements, the new Time series panel implements new features like line interpolation modes, support for more than two Y-axes, soft min and max axis limits, automatic points display based on data density, and gradient fill modes.

 _Node graph_ is a new panel type that can visualize directed graphs or network in dashboards, but also in Explore. It uses directed force layout to effectively position the nodes so it can help with displaying complex infrastructure maps, hierarchies, or execution diagrams.

 You can now provide detailed information to alert notification recipients by injecting alert query data into an alert notification. Labels that exist from the evaluation of the alert query can be used in the alert rule name and in the alert notification message fields. The alert label data is injected into the notification fields when the alert is in the alerting state. When there are multiple unique values for the same label, the values are comma-separated.
