We likely need a defined set of icons that match the schemas used across our apps. The immidate need is data grid, but this stuff indirectly goes into everything in Kibana from Lens to Discover.

I don't know whether we should use tokens or colored icons for this stuff. Here's a list of stuff I know we'd need. A lot of these have icons already

• String (string)
• Number (number)
• Geo (globe)
• Boolean (invert)
• JSON/Object
• Date (calendar)
• Currency
• URL (link?)

Beyond that, I could see us filling this in with ECS definitions. Likely the top level field types would be a good reference. https://www.elastic.co/guide/en/ecs/current/ecs-field-reference.html
