In his up-voted answer to Software needed to scrape data from graph, Alexey writes (with respect to the need for data scraping off of raster graphs) "But nowadays the good practice is to publish graphs in vector form."
To rip off my comment to Alexey from that page: Is there a good reference for best practices around which vector format(s) to present graphs of data in? For example, ought I use an eps encapsulation of an svg file in my LaTeX manuscripts, or am I supposed to output graph in LaTeX directly? Or something else?
