The Elastic developer community is quite vibrant, and new releases with new features/fixes get released quite often. While you have been reading this book, the latest Kibana version might have changed. The instructions in this book are based on Kibana version 7.0.0. You can click on the past releases link and download version 7.0.0 (kibana-oss) if you want to follow as is, but the instructions/explanations in this book should hold good for any 7.x release.
Kibana is a visualization tool that relies on Elasticsearch for querying data that is used to generate visualizations. Hence, before proceeding further, make sure Elasticsearch is up and running.
