[Rahul-0108]

Can We integrate deck.gl to show custom map layers on the viewport ??

No, but iTwin.js already supports map layers (beta).
@mdastous-bentley are any samples, sandboxes, tutorials, or documentation overview available?

Basically , I want to render any type of geojson feature like linestring , polygon, MultiLineString on the map ,
Also I want to render 3D map layer on the viewport like this based on the data:

Please let me know how can we add additional map layers or view decorations is the way to do this ??
