A very simple GeoJSON viewer that loads an url from the hash and renders it with leaflet. The URL of the GeoJSON file must support CORS. If it doesn't you can just proxy it through https://crossorigin.me/.

I whipped this up just to visualize some of my own GeoJSON API endpoints so this is super janky. Also, it requires modern browser support because I wrote ES6 out of habit and am not transpiling.
