Trying to do geocolor and not sure what I'm missing

[bartonhammond]

Thanks for your help! It took me a little longer to get all the data together.

I can load this map on http://geocolor.io/# but all I see are dots rather then regions being colored.

The input file:
heatmap.geojson.zip
The code:

var geocolor = require('geocolor');

var fs = require('fs');

try {
  var heatmap = JSON.parse(fs.readFileSync('./heatmap.geojson'));
} catch (err) {
  console.log('err',err);
}

var z = 'stars',
    numberOfBreaks = 5,
    colors = ['red', 'blue', 'white'];

// jenks
var geoJenks = geocolor.jenks(heatmap, z, numberOfBreaks, colors);

fs.writeFileSync('./jenks.geojson', JSON.stringify(geoJenks));

My output Jenks.json:
jenks.geojson.zip

So I update zoom when building the tiles and add a feature.properties["marker-color"] = "#55aa00";

So now, http://bl.ocks.org/anonymous/raw/c331c007fa82a8248053 I'm seeing markers that are blocks. I'm assuming that's because we used

tilebelt.pointToTile(star.long, star.lat,
                                  zoom).join('/');

So I'm trying to figure out what I need to get "countries" to be lit up.

Wanted to share what I have now. The icons are colored from geoColor.
