Accessing properties of Geometry objects when using AlbersUsa projector
I'm looking at the Globe Albersusa example and noticed that the properties of Geometry object is not available after feature_from_name returns. I need to access these properties to assign/map the FIPS county ID to each SVG subcomponent so I can map specific data to each county.
Here's the equivalent code in JS does this automatically without having to do any manual mapping:
ex:
// Draw county boundaries and fill accordingly
svg.selectAll("path")
.data(feature(usCounties, usCounties.objects.counties).features)
.enter().append("path")
.attr("d", path)
.attr("fill", d => {
const countyData = countyToData[d.id];
console.log(d, countyData);
if (countyData) {
return d3.color(colorScale(countyData.rise));
}
return "darkgrey";
})
.attr("stroke", "#ffffff") // color of the border
.attr("stroke-width", "1.0"); // thickness of the border;
How can i do something similar with d3_geo?
