I am making a choropleth map of population estimate by counties in United States. I am almost done but the problem is a few counties have population count in seven figures and they are the ones that are not being filled. Can somebody help me fix that? I think something's wrong with this part of the code.

var color = d3.scaleThreshold()
.domain(d3.range(2,10).map(function(d) { return d * 1000; }))
.range(d3.schemeReds[9]);

Here's a link to my Gist on Github https://gist.github.com/sabeehtaqi/3c680626970a66ad63058b08f2a042a4

  • Disclaimer, I don't know d3 or javascript, but just looking at your block of code, my guess is that you need to change the part of the code that multiplies d by 1000. Change it to: return d * 10000 or return d * 100000. That might include the counties with the larger populations. – Fezter May 22 '17 at 0:44
  • Thanks for the quick response @Fezter but that just changes the color range of the population, that still doesnt include those counties. – user97648 May 22 '17 at 0:55

  • What about this part of your code? var x = d3.scaleLinear() .domain([0, 10000]) .rangeRound([650, 1000]); on lines 16-18? Is the domain large enough? – Fezter May 22 '17 at 1:26
