I can't seem to find any documentation on how to edit the maps style that ships with Splunk 6. Can this be accessed via CSS? If so, could anyone tell me what the parameters are? I'm trying to edit the look like the Google Maps dark style non-terrain (clean/basic look).
As far as I know, all the properties you can change for maps are covered in the simple XML reference docs. There might be other tile sets you can use that give you additional flexibility, or fancier customizations you could do with the web framework, but someone smarter than I am would have to give you suggestions about that.
