Signups for BOT(N|S) end today (16th October), check https://conf.splunk.com/connect/boss-of-the-soc-and-noc.html There are also frequent regional BOT(N|S) that are run, more details on the website.
Past datasets for BOTS can be found at https://github.com/splunk?q=bots , and many related Splunk Blog posts about it can be found at https://www.splunk.com/en_us/blog/tag/boss-of-the-soc.html,. These are freely avaialable, just download the data, copy to a Splunk instance (also free, as the data is already ingested), and you're good to go and start practcing.
Disclaimer, I work for Splunk, and am helping coach in the APAC BOTN next week.
I'll also link to the Splunk Attack Range, https://github.com/splunk/attack_range . This allows you to quickly spin up a small lab environment, then quickly hit it with a bunch of realistic attacks. All that data is then is then sent to a prebuilt Splunk instance for you to practice your investigation and analysis, and even integrate with Phantom, Splunk's automation system. Check out the video for it at https://www.youtube.com/watch?v=xIbln7OQ-Ak . Again, this is all free, no registration required.
It integrates an editor where you can convert query results to such visualizations. You could also integrate your custom viz made with JS libs (D3).
Entreprise Security is a Splunk paid app that provides a nice environment for SOC analysts.
Yes,you should give it a try, maybe through a docker image that will get you going quickly.
