I am adopting the code for the brushable scatter matrix using d3 and jsdom on server side to generate the SVG.

SVG is perfectly generated.

However in the node script I am also binding data to some svg elements that is later used on the client side for mouse events interaction.

Here is (the well known) snapshot:

var cell = svg.selectAll(".cell")
    .data(cross(traits, traits))
    ...

At the end I am just saving the generated HTML to a file using

jsdom.window.document.querySelector("html").outerHTML;

which doesnt actually save __data__ property of the .cell elements.

Of course any method invocation that uses these values on client side fails with undefined.

On the server side on debug I can perfectly see __data__ property assigned to each of my svg elements.

I am just wondering is there any way to tell jsdom to export/save even the properties stored during generation or it can be done later only on client side???
