Bugs in graph tutorial

[alexung]

Hey all,

Thanks for putting this together -- much appreciated. Am going through the graph tutorial at the moment and have a blank screen with no visible errors in the console.

Also am trying to keep up to date with the newest releases of deck.gl and after updating my npm package to "deck.gl": "^6.0.3", it seems that OrthographicViewport can now be substituted with OrthographicView, which DeckGL can include with propview as opposed to viewport.

New viewport in createViewport():

return new OrthographicView({ width, height, left: (-width / 2), top: (-height / 2) });

I'm not getting anything showing up on the screen with these changes in place. I do see something, however, when I comment out getSourcePosition() in createEdgeLayer():

Curious as to what's going on -- no nodes are visible? Would appreciate assistance.

Update When going into lesson 3 of tutorial I get also a blank screen with the following error on console:

Uncaught TypeError: u.OrthographicViewport is not a constructor
