What are the options to programmatically create a graph in png / jpg format?

Question

JPEG

I would like to insert a graph into the email that we send out.
The graph is personalized, that is, it must be programmatically generated from the server according to the model, and received in image format.
Maybe someone knows how this can be achieved?

Answer 1

Obviously, you need to use SVG, and more precisely, for graphs, it’s better to use D3.js

Answer 2

If you prefer raster, you can use www.gnuplot.info on the server
