Stumbled on this old pile of code from the mid-point of my PhD work. I wanted to see what venues WWW-published authors also published in, because I wanted to be published in WWW---but only one publication deadline per year is not enough.
adjacent-confs.py downloads that data from DBLP. No idea if it still works. It was last edited in December 2017.
Similar Venues.ipynb does some visualization. If it won't load on Github, you can view it here
