Very cool app. Here is the graph for my 4 favorite male GMs. It's interesting that Ivanchuk brieflly caught up with Anand.

The first version of the app was quite rough. All more than 300 players were listed in one endless list.
I separated players so that they can be selected by their initial letter.
Clicking on 'C' will bring up players with initial letter 'C':
It was no easy to unselect players, so I added a new pane in which you can unselect already selected players one by one, or all at once:
I also added a settings panel in which you can ajust the chart size to your browser window and select the start year of the chart allowing you to view recent performance of players more closely:
The first version collected players by name. This had the drawback that due to misspelling some players appeared under several different names and you had to select all of them to put together the chart ( which then consisted of differently colored chart segments for the same differently spelled player ). Now histories are collected according to Fide ID. I picked the correctly spelled version of each player's name and attached this to their ID, letting you have correctly spelled names.
Fide no longer offers the rating charts of players and when it did these were for only a limited period and only for one player at a time. I obtained all publicly available Fide rating lists for the 2001-2016 period and collected the rating history of all players that ever reached a Top 100 ranking during this period ( this is 316 players ).
Using this interactive application you can select any number of these 316 top players and view their comparative rating history chart:

This application uses a free RStudio account with limited running time. Once it expires it is not available until the next monthly period. If it is unavailable I can still post such charts on demand as images here in this thread.
