How can I resize my d3.js script? is there a way to put this into a div tag where I can resize my bar chart smaller?

Question

i am unable to resize my bar chart within a script tag. Currently the bar chat is showing up massive on the page and I would like to resize the chart into a smaller size on the page.

Is there a way to resize this using CSS or JavaScript or put it into a Div? I tried to give the script tag a 'id' or 'value' but no luck.

Could someone help me resize my chart please.

this is me d3.js:

<script>

    data = [
        {label:"Jan Sales", value:35},
        {label:"XMAS", value:5},

    ];

    var div = d3.select("body").append("div").attr("class", "toolTip");

    var axisMargin = 20,
            margin = 40,
            valueMargin = 4,
            width = parseInt(d3.select('body').style('width'), 10),
            height = parseInt(d3.select('body').style('height'), 10),
            barHeight = (height-axisMargin-margin*2)* 0.2/data.length,
            barPadding = (height-axisMargin-margin*2)*0.6/data.length,
            data, bar, svg, scale, xAxis, labelWidth = 0;

    max = d3.max(data, function(d) { return d.value; });

    svg = d3.select('body')
            .append("svg")
            .attr("width", width)
            .attr("height", height);


    bar = svg.selectAll("g")
            .data(data)
            .enter()
            .append("g");

    bar.attr("class", "bar")
            .attr("cx",0)
            .attr("transform", function(d, i) {
                return "translate(" + margin + "," + (i * (barHeight + barPadding) + barPadding) + ")";
            });

    bar.append("text")
            .attr("class", "label")
            .attr("y", barHeight / 2)
            .attr("dy", ".35em") //vertical align middle
            .text(function(d){
                return d.label;
            }).each(function() {
        labelWidth = Math.ceil(Math.max(labelWidth, this.getBBox().width));
    });

    scale = d3.scale.linear()
            .domain([0, max])
            .range([0, width - margin*2 - labelWidth]);

    xAxis = d3.svg.axis()
            .scale(scale)
            .tickSize(-height + 2*margin + axisMargin)
            .orient("bottom");

    bar.append("rect")
            .attr("transform", "translate("+labelWidth+", 0)")
            .attr("height", barHeight)
            .attr("width", function(d){
                return scale(d.value);
            });

    bar.append("text")
            .attr("class", "value")
            .attr("y", barHeight / 2)
            .attr("dx", -valueMargin + labelWidth) //margin right
            .attr("dy", ".35em") //vertical align middle
            .attr("text-anchor", "end")
            .text(function(d){
                return (d.value+"%");
            })
            .attr("x", function(d){
                var width = this.getBBox().width;
                return Math.max(width + valueMargin, scale(d.value));
            });

    bar
            .on("mousemove", function(d){
                div.style("left", d3.event.pageX+10+"px");
                div.style("top", d3.event.pageY-25+"px");
                div.style("display", "inline-block");
                div.html((d.label)+"<br>"+(d.value)+"%");
            });
    bar
            .on("mouseout", function(d){
                div.style("display", "none");
            });

    svg.insert("g",":first-child")
            .attr("class", "axisHorizontal")
            .attr("transform", "translate(" + (margin + labelWidth) + ","+ (height - axisMargin - margin)+")")
            .call(xAxis);

</script>

This is my CSS:

    svg {
        width: 100%;
        height: 100%;
        position: center;
    }

    .toolTip {
        font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
        position: absolute;
        display: none;
        width: auto;
        height: auto;
        background: none repeat scroll 0 0 white;
        border: 0 none;
        border-radius: 8px 8px 8px 8px;
        box-shadow: -3px 3px 15px #888888;
        color: black;
        font: 12px sans-serif;
        padding: 5px;
        text-align: center;
    }

    text {
        font: 15px sans-serif;
        color: white;
    }
    text.value {
        font-size: 100%;
        fill: white;
    }

    .axisHorizontal path{
        fill: none;
    }

    .axisHorizontal .tick line {
        stroke-width: 1;
        stroke: rgba(0, 0, 0, 0.2);
    }

    .bar {
        fill: steelblue;
        fill-opacity: .9;
    font-size: 120%;
    }

Add a viewBox attribute to the svg element. This will allow you to lock the svg to the exact dimensions of your graph using the min-x, min-y, width and height parameters.

Then you can resize the svg element and you're graph will stretch to grow bigger or smaller.

Edit: Here is your js fiddle updated to use viewBox. I've commented out the width and height attributes so that it resizes as you make the page wider or narrower.

Is this the sort of thing you're looking for?
