This is an excerpt from a mail by the paper co-chairs for EuroVIS to the full paper track reviewers. Definitely worth a read.
Especially for the younger reviewers we would like to point to recent blogs of Niklas Elmqvist (https://sites.umiacs.umd.edu/elm/2016/02/01/mistakes-reviewers-make ) and John Stasko (https://jts3blog.wordpress.com/2016/12/23/tips-for-being-a-good-visualization-paper-reviewer/ ), who give many highly useful and valuable recommendations for reviewing visualization papers.
