How can I remove or replace SVG content

Question

I have a piece of JavaScript code which creates  using D3 js  an svg element which contains a chart  I want to update the chart based on new data coming from a web service using AJAX  the problem is that each time I click on the update button  it generates a new svg  so I want to remove the old one or update its content   Here is a snippet from the JavaScript function where I create the svg   var svg   d3 select  body            append  svg            attr  width   w           attr  height   h     How can I remove the old svg element or at least replace its content

You should use append  svg svg    not append  svg   so that D3 makes the element with the correct  namespace  if you re using xhtml
