Node and headless

[nnylip]

I currently use jqplot for both mobile and desktop apps with great satisfaction. I am wondering if either of the following exist:

1. a method by which charts could be created "offscreen". This is needed as there is a scenario where multiple charts need to be created and then inserted into pdfs for user reporting. This is currently done by sequentially displaying the charges by sliding them across the screen, capturing the image and then putting them into the pdf. It would be much more user friendly to do this offscreen.
2. a version or consideration for a version that would operate in a node server environment whereby it would be possible to create a chart(s) as part of a script. Similar to 1, this would have to be done in a "headless" environment, the chart grabbed as a jpg and then inserted into a pdf.
   In both these cases, code reuse is what is being targeted, i.e. reuse of exisitng mobile or desktop code. Further explanation can be provided. thanks
