Vega declarative grammar is a powerful way to visualize your data. Let’s learn Vega language with a few simple examples.

Continuing the series on building custom Vega graphs in Kibana, our today’s topic is a simple two level Sankey graph to show network traffic patterns.

The graph will have two modes: all-to-all (default), plus it will allow users to select either the source or the destination country, and show only related traffic.

There are plenty of pending requests for Kibana visualizations. Now with Vega support, we no longer need to wait, anyone can do most of them by themselves! This is the first in a series of blog posts on how to build Vega visualizations in Kibana.

Vega offer a way to create custom visualizations, beyond the ones that come standard with Kibana. In this post we will use Vega-Lite (simplified Vega) syntax to show data from Elasticsearch.
