I've also found that a Zeppelin style hides any geoJSON boundary type overlays. The offending rule seems to be the following, removing this in chrome dev tools makes the overlay appear. YMMV... ..\zeppelin-web\src\app\notebook\paragraph\paragraph.css .paragraph div svg { width: 100%; } ... View more

I've found that in Zeppelin 0.7.0 the geoJSON needs to be obtained without credentials, otherwise an access control error results : "The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'" which is I guess new behaviour in Zeppelin. As there doesn't seem to be a way to configure $.getJSON to do this, load it as follows : $.ajax({ url: "https://raw.githubusercontent.com/BrooksIan/DS_GTDB/master/json/Mesa.geojson", dataType: "json", xhrFields: { withCredentials: false } }) .done( function( data ) { L.geoJson( data ).addTo( map ); }); Hope this helps, Simon ...
