i trying show different countries , citywise population using stacked bar chart data set being unique cities , countries being uniquely exclusive each other chart showing first data in set per code. how make work show data in different stacked bars each country. here code have tried far : https://jsbin.com/qopazukahi/edit?html,output.
below dataset:
var data=[ { "country": "india", "delhi": 310504, "kolkata": 552339, "chennai": 259034, }, { "country": "australia", "melbourne": 62083, "sydney": 85640, "perth": 42153, "canberra": 74257, }, { "country": "usa", "new york": 415910, "miami": 828669, "frankfort": 362642, "portland": 601943, "topeka": 1804762, }, ]; here complete code:

needed consider data[] indexes present in data array below:
data.foreach(function(d,i) { var y0 = 0; d.ages = d3.keys(data[i]).filter(function(key) { return !key.match(/country/); }).map(function(name) { return {name: name, y0: y0, y1: y0 += +d[name]}; }); here workig bin : https://jsbin.com/qopazukahi/edit?html,output
