TopoJson is not rendered on map

[li-shasha]

currently topojson data is not rendered on map even with component vl-source-vector :format-factory property and :overlap=false

wasser.json is a topology json data.

<vl-source-vector :url="/maps/wasser.json" :format-factory="createTopoJsonFmt" :overlaps="false"></vl-source-vector>

...

import {TopoJSON} from 'ol/format';
...
methods: {
  createTopoJsonFmt(){
    return new TopoJSON({})
  }
}

can you help to check it please? you can see the topojson with mapshapper or whatever you like. sandbox example

Hi @li-shasha , the topojson file not work even with openlayers https://jsfiddle.net/ghettovoice/sdx98e2f/42/. If you check in the console created features, you will see that some of coordinates have Nan value. Usually this due to incorrect projection.

vuelayers work with topojson. It just need proper data projection
