and code

  var tex_info = ["6-12m_a", "6-12m_b", ">12m_b", ">12m_a", "0", "<6m_b", "<6m_a"];   var w = 500;   var h = 200;   tex_info.foreach(function(item_list) {     dataset[item_list].foreach(function(item) {     d3.select("#chart2").selectall("div")       .data(item["count"])        .enter()       .append("div")       .attr("class", "bar")       .style({"height": function(d) {           var barheight = d*5;           return barheight + "px";       }, "width": "2%", "background-color":"blue","display":"inline-block", "margin-right": "0.5px", "margin-left": "0.5px"});     });   });

i want use each tex_info item represente x component in xasis each item of tex_info dictionary in dataset 10 values, want representing each values bars on each xasis, when try represent bar don't return nothing.

<div id="chart2"></div>

i try same example using svg

 var svg = d3.select(".svg")             .append("svg")             .attr("width", w)             .attr("height", h);  d3.json("....", function(json) {   tex_info.foreach(function(list) {     json[list].foreach(function(item){       console.log(item);     svg.selectall("rect")        .data(item)        .enter()        .append("rect")        .attr("x", 0)        .attr("y", 0)        .attr("width", 20)        .attr("height", 100);     });   }); });

any idea how solvent issue.
