VegaLite is a simplified version of Vega, useful to quickly get started, but has a number of limitations. VegaLite is automatically converted into Vega before rendering. Compare logstash-simple_line-vega and logstash-simple_line-vegalite (both use the same Elasticsearch logstash data). You may use this editor to convert VegaLite into Vega.
IMPORTANT: No additional bug fixes or documentation updates will be released for this version. For the latest information, see the current release documentation.
