I was able to figure out how to install the custom visualization. To help others, the only reference I could find is in this video (https://www.bing.com/videos/search?q=how+to+install+tgz+in+splunk+for+windows&docid=608027228300116478&mid=BA8C2B8EA0DCF1EF028FBA8C2B8EA0DCF1EF028F&view=detail&FORM=VIRE). I could not find documentation on this procedure.
As for the JS approach I still can't get it working. I understand now that the .JS file is not being found at all. I then tried a simpler example from https://answers.splunk.com/answers/579537/how-to-use-javascript-code-in-splunk-cloud-dashboa.html, and I could not get that working either. In that example the F12 debugging states:
Failed to load resource: 8000/en-US/static/@a6754d8441bf/app/hello-splunkjs/hello_world.js:1 the server the server responded with a status of 404 (Not Found)
The message is confusing because that path doesn't map to my E:/Program Files/Splunk/apps directory. Also there's an etc/apps directory and a etc/users/paul directory which can both have App stuff in them. I don't understand where all the associated files go for that example. Can you help me understand?
