I'm trying to render a US Zip Code map similar to the one in this blocks article http://bl.ocks.org/jefffriesen/6892860. However, we are using d3 v5 and topojson 2 to render our chloropleth. I've tried using the same json file in the article listed above and creating my own TopoJSON from the US Census shapefile as described in this article https://medium.com/@mbostock/command-line-cartography-part-1-897aa8f8ca2c
When my path elements render they all start with a negative number.
