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.

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.
