Cartographic Visualization in Vega-Lite

A series of notebooks to introduce Vega-Lite in Observable

Intro to Vega-Lite

Hello, apparently at least one of the features has the “wrong” winding-order. See https://observablehq.com/@fil/rewind for explanations. The map is fixed by calling data(vl.json(rewind(seattleNeighborhoodsGeojson)) with 
import {rewind} from "@fil/rewind"

Thanks Fil. I'll try this fix when I get a chance.
