Nvd3js - TypeError: data.map не является функцией

Я пытаюсь отобразить график Stacked nvd3js (http://nvd3.org/examples/stackedArea.html) и продолжает получать эту ошибку:

state.disabled = data.map (функция (d) {возврат !! d.disabled});

сложены... hart.js (строка 87, столбец 6))

мой пример json:

var data = [

и код nvd3js:

//NVd3js
function defaultChartConfigBS(container, data, useGuideline) {
  if (useGuideline === undefined) useGuideline = true;
  nv.addGraph(function() {
    var chart;
    chart = nv.models.stackedAreaChart()
                  .useInteractiveGuideline(useGuideline)
                  .x(function(d) { return d[0] })
                  .y(function(d) { return d[1] })
                  .useInteractiveGuideline(true)    //Tooltips which show all data points. Very nice!
                  .rightAlignYAxis(false)      //Let's move the y-axis to the right side.
                  .transitionDuration(500)
                  .showControls(true)       //Allow user to choose 'Stacked', 'Stream', 'Expanded' mode.
                  .clipEdge(true)
                    ;

    chart.xAxis
        .tickFormat(function(d) { return d3.time.format('%x')(new Date(d)) });


    chart.yAxis
        .tickFormat(d3.format(',.2f'));

    d3.select('#' + container + ' svg')
          .datum(data)
           // .datum( [data()[0].values] ) tried the hack from stack - didnt help
        .transition().duration(20).call(chart);

    nv.utils.windowResize(chart.update);


    return chart;
  });
