this iteration uses the Robinson Projection from d3-geo-projection
it also uses a threshold scale with manually specified breaks to map values in the data to colors on the choropleth map
🎩 @jeremy_cf_lin for suggesting the Robinson Projection over in the #help channel of the d3js slack
do check out the other examples in this world map series:
world map 00 original example
world map 01 fix tooltip value
world map 02 d3 v4
world map 03 es2015 + update code style
world map 04 manual breaks + threshold scale
world map 05 linear breaks + quantize scale
world map 06 linear breaks + quantiles scale
world map 07 Jenks natural breaks
world map 08 ckmeans cluster max breaks
world map 09 ckmeans cluster min breaks
forked from micahstubbs‘s block: world map 04 manual breaks + threshold scale
forked from Fil‘s block: world map 04 manual breaks + threshold scale d3v5 [UNLISTED]
