— Overall performance is below average.

— Sloppy on vertical scrolling.
— The app is slow when filtering and scaling.
— Y-scale starts from zero (graph #1 and #2).
— Vertical scrolling doesn't work unless you aim outside the graphs.
— The graphs take the entire width of the page when viewed from desktop browsers.

1) Enable responsive mode in DevTools or open this page from mobile device
2) Just place your finger down on the minimap and move finger

40 fps on desktop. Poor
Yes, I can see the performance lags too, but I think those are due to some honest mistake of not removing some of the console logs from the code. I think that without the logs the app would be much faster.

And yes, the mouse events are not supported unfortunately, but I think that is a small issue - they can be easily added. Touch events work fine (well, not the long touch - it was not realized, but the other touch events work fine)

Nobody added any issues yet...
