javascript - Unable to select data with d3.defer -

-

i'm stuck stupid problem in d3 map. load 2 files, , fine, colors here, etc. however, i'm not able adjust opacity, because takes data in json, not in csv, if/else. here sample of code:

queue()     .defer(d3.json, "data/countries.json")     .defer(d3.csv, "data/data.csv")     .await(ready);  function ready(error, map, data) {   if (error) throw error;    var ratebyid = d3.map();    var paths = g.append("g")     .attr("class", "countries")     .selectall("path")     .data(topojson.feature(map, map.objects.countries).features)     .enter()     .append("path")     .attr("opacity", function(d) {         var value = data.id;        if (value) {          return ".8";        } else {           return ".1";         }      })     // ...  });

any idea how aim correctly "id" column in data.csv? thank you.
