Kibana Visualization plugin for displaying a funnel.
Based on D3 Funnel lib - https://github.com/jakezatecky/d3-funnel

Kibana version v7.4.0

Run node ./scripts/kibana_plugin.js install https://github.com/outbrain/ob-kb-funnel/releases/download/v7.4.0/ob-kb-funnel-7.4.0.zip

Once installed, you'll see an additional type of visualization, named "Funnel View". The funnel can be constructed from two types of aggregations: 'By Buckets' and 'By Metrics'

• 'By Buckets' - Every slice in the funnel is a bucket. You should define 1 metric and 1 bucket Aggregation.

• 'By Metrics' - Every slice in the funnel is a different metric. You should define several metrics, without bucket aggregations.

Advanced D3-funnel options can be set in the Options tab, along with other funnel options.
