You can make the chart resize using a combination of viewBox
and preserveAspectRatio
attributes on the SVG element.
See this jsfiddle for the full example: http://jsfiddle.net/BTfmH/12/
var svg = d3.select('.chart-container').append("svg")
.attr("width", '100%')
.attr("height", '100%')
.attr('viewBox','0 0 '+Math.min(width,height)+' '+Math.min(width,height))
.attr('preserveAspectRatio','xMinYMin')
.append("g")
.attr("transform", "translate(" + Math.min(width,height) / 2 + "," + Math.min(width,height) / 2 + ")");
You won’t even need a resize
handler with this method.
