When I click a button, I pass an array of data from a viewmodel. On the d3.json function, I use json_encode against the viewmodel to tranform it to a JSON object. When I inspect it on the page, it does convert it but I am getting an

"Uncaught SyntaxError: missing ) after argument list".

Can someone tell me what I am doing wrong?

d3.json("<?php echo json_encode($viewmodel) ?>", function(error,data){
        data.forEach(function(d) {
          d.projectdate = parseDate(d.projectdate);
          d.Cost = +d.Cost;

          var svg ="body")
                      .attr("id", "chart")
                      .attr("width", w)
                      .attr("height", h);

                .classed("bar", true)
                .attr("x", 0)
                .attr("y", function(d, i){
                    return i * 20
                .attr("width", function(d,i){
                    return d;
                .attr("height", 20);

    d3.json() expects a url as its first parameter, not a JSON string. This will in turn request the specified file at that particular url to load the JSON from.

    In your case, however, it might be easier to directly assign the JSON to the data variable.

    var data = JSON.parse("<?php echo json_encode($viewmodel) ?>");
    data.forEach(function(d) {
