I'm new to D3, and spent already a few hours to find out anything about dealing with structured data, but without positive result. I want to create a bar chart using data structure below. Bars are drawn (horizontally), but only for user "jim".

var data = [{"user":"jim","scores":[40,20,30,24,18,40]},
            {"user":"ray","scores":[24,20,30,41,12,34]}];

var chart = d3.select("div#charts").append("svg")                                   
              .data(data)
              .attr("class","chart")
              .attr("width",800)
              .attr("height",350);

chart.selectAll("rect")    
    .data(function(d){return d3.values(d.scores);})    
    .enter().append("rect")
    .attr("y", function(d,i){return i * 20;})
    .attr("width",function(d){return d;})
    .attr("height", 20);

Could anyone point what I did wrong?
