> @nielsen-at-cgt Vega-Lite does not have a good built-in handling of nested data results, so I would advise you use [composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html). See an example in the video linked from the recent [Vega blog post](https://www.elastic.co/blog/custom-vega-visualizations-in-kibana). If you need to process nested data, you can use full Vega language instead - the ["group" mark](https://vega.github.io/vega/docs/marks/) can be used to draw pre-faceted data.
