Word Tree Memory usage

[Nathan Hughes]

Hi,

I have noticed that with a data set of  500 records the Word Tree Chart uses a lot of memory

In simple Javascript page, it inflates to over 400mb, a memory trace shows that almost all of the memory is being used by the SVG object and several gvjs elements.

This is compounded if you use the chart within an angular directive, the memory tops out at 1.7gb, this is the same whether I:

Use the ng-google-chart.js library or my own directive.

It also makes no difference how I construct the data table.

Has anyone else experienced this? And are there any strategies for reducing this?
