Another way to achieve this can be overriding the style using CSS. Simply add class below to your stylesheet:

.highcharts-legend-item rect {
    width: 12px;
    height: 12px; /* height = width */
    rx: 50%;
    ry: 50%;
}

and this would override the default style for the SVG Rectangle element.

There's quite an easy fix. Just set the following properties in chartoptions:

chartoptions.legend.symbolHeight = 12;
chartoptions.legend.symbolWidth = 12;
chartoptions.legend.symbolRadius = 6;

For further reference, check highcharts api documentation.

Checkout this jsFiddle.

In recent versions of Highcharts you can use symbolWidth: width and symbolRadius: width/2 inside legend: {}.

See this JSFiddle demonstration: http://jsfiddle.net/Wzs9L/

I prepared solution based on pie chart. Legend is generated on data points, automatically as HTML list. Then all elements gets colors from series, and use CSS3 to generate circle object (border-radius). As a result you need to add click event.

http://jsfiddle.net/N3KAC/1/

 $legend = $('#customLegend');

    $.each(chart.series[0].data, function (j, data) {

        $legend.append('<div class="item"><div class="symbol" style="background-color:'+data.color+'"></div><div class="serieName" id="">' + data.name + '</div></div>');

    });

    $('#customLegend .item').click(function(){
        var inx = $(this).index(),
            point = chart.series[0].data[inx];

        if(point.visible)
            point.setVisible(false);
        else
            point.setVisible(true);
    });

CSS:

    .symbol {
    width:20px;
    height:20px;
    margin-right:20px;
    float:left;
    -webkit-border-radius: 10px;
    border-radius: 10px;
}
.serieName {
    float:left;
    cursor:pointer;
}

.item {
    height:40px;
    clear:both;
}
