Unusable on mobile. In portrait, the sidebar covers everything; in landscape, it still covers half the viewport, and touch panning works but resets the position of the graph to what I assume is center or origin on every drag.
Hate to seem harsh, but I felt it worth mentioning, since it's why I'm unable to give any more substantive feedback on the project.
Not at all designed to be compatible with mobile.
Cool visualisation, but it doesn't have links to the subreddits?
