We have a map view taking a GeoJSON feed and plotting points according to long/lat. It works really well, but the out of the box symbols provided don't match our data use-case (weather events etc). I'm capable of creating my own SVGs, but I'm wondering where these files reside on the ES/Kibana hosts. I imagine the existing symbols are all just SVGs sitting in a directory, so in theory it should be easy enough to add more.
Short of doing a massive scan over the directory structure (which will produce thousands of false leads), does anyone know the path to the symbols files, or any other methods for adding these in?
