Hi ECharts, was good meeting some of you at ApacheCON. Recommended SVG publishing followup

Hi ECharts,

Was good meeting some of you at ApacheCON. EChats looks amazing. Its even better than D3&Vega.

I talked with Ovilia for a while after her Echarts presentation about backend/server side publishing of SVG. My understanding from conversations with Ovilia is that server side rendering of Echarts->SVG isnt supported.

At Bloomberg, our PDF report generation systems all run on the back end server.  A PDF contains many charts and graphics. We use SVG and converted it into Adobe PDF vectors because PNG/BMP pixelate and look horrible on large monitors or good quality printers.

Is there any interest in the Echarts community to support server side rendering of Echarts->SVG?

I assume this is an npm NodeJS package but which one?

I am sure the answer is on Google search somewhere but English and Echarts is hard to follow the right threads.

I think we should probably provide a npm cli tool to help users generate
SVG files in command line.

Erik, do you need a tool to generate PDF containing ECharts charts? If you
need something else like annotation, this may be not easy to do. But if you
only need charts and chart descriptions, I think it is possible to provide
such PDF generation tool.

Hi Erik

ECharts didn't plan to support server-side SVG rendering directly because
there is no DOM environment in the node.js.

But I tried to use JSDom to simulate the DOM environment in the node.js,
then run ECharts with SVG renderer. It works well.
Here is a code snippet in the gist:

https://gist.github.com/pissang/4c32ee30e35c91336af72b129a1a4a73

You can run it with node-canvas and JSDom installed. Hope this helps.

Best regards.
