Are you just looking for press kit resources? There's a somewhat dated press kit available from https://github.com/250/Steam-Top-250/releases/download/press... that might contain some useful images. If you're looking for something more specific, let me know!
Charting game ranking history is my personal favourite upcoming feature. I want a graph with the full history of a game's ranking across all rankings, so you can easily see how many segments it's participating in both past and present. However, another limitation of the current infrastructure is we don't have a persistent data store. Every day we create a new, independent database snapshot containing only that day's data. Once again, this feature will take several months to develop, mainly because I have to go back to work now because I didn't receive enough funding via Patreon, but I'm looking forward to it at least as much as you :)
