The 3-dimensional plots in SageMath are quite good, and easy to use. In particular moving the camera angle interactively in the sage worksheet is very helpful. But I can't figure out how to output the image as .svg or .pdf...
The journal requires .svg or .pdf. I can re-compute all the figures in SageMath, but I can't figure out how to output an .svg or .pdf. Is there a way?
