I am planning to export c3 charts using https://github.com/Xportability/css-to-pdf. But CSS2PDF requires the SVG tags to contain attributes xmlns="http://www.w3.org/2000/svg" and xmlns:xlink="http://www.w3.org/1999/xlink" to be a valid for export.
How to add these two attributes to svg element generated by c3 chart ?
$(document).ready(function () {
var svg = $('#chart').find('svg')[0];
svg.setAttribute('xmlns', 'http://www.w3.org/2000/svg');
svg.setAttribute('xmlns:xlink', 'http://www.w3.org/1999/xlink');
});
