How do I load Google Charts in node.js?

阅读更多关于 How do I load Google Charts in node.js?

When I attempt to load a Google Chart in node.js, nothing happens. I tried loading the first example from the line chart docs in both zombie.js and jsdom, but the chart never loads in either case. The end goal is to retrieve the SVG data of the generated chart for export into an image or PDF. So if an alternate method (server side using node.js or PHP) to achieve this is possible, I'm open to suggestions. NOTE : I have successfully generated a images of a few charts using gChartPhp, but the requirements of this project state that the embedded version be the interactive version provided by the

问题 I am trying to use ajax-seo for an Angularjs app to serve html compiled content from a PhantomJS webserver`. But it's not rendering the complete page. It's just giving the following response <html><head></head><body></body></html> I have followed the instructions well but no luck so far.
