Before I updated, I would run my script and output the html file. There would be my one plot in the window. I would make changes to my script, run it, output the html file, look at the new plot. Then I installed the library again to update it using conda. I made some changes to my script, ran it again, and the output file included both the plot before I made some changes AND a plot including the changes. I ran the script again out of curiosity. Three plots in the one file! Ran it again. Four! Deleted the html file (instead of overwriting). Five! Changed the name of the output html file. Six! I even tried changing the name of the script. The plots just keep piling up.

What's going on? Why is it plotting every version of the graph I've ever made?
