I don't seem to be able to zoom with the source you provided!

Haha, oops. I just added mouse wheel event support for firefox in the latest commit: https://github.com/aantthony/graph.tk/commit/ff98c9a8bfb0de1e22753c8d8eefd49c7f0ea0bc

Hopefully it works now?

[geoffmomin]

Yep it works! It really is a great app...

Sorry, but it seems to have trouble zooming in Google Chrome and Safari...im basically running tests on all browsers and am trying to get it working on the iPad and iPhone!

Thanks :) It works for me on Chrome and Safari but I'm using the mac version. Does this page scroll?: http://aantthony.github.com/graph.tk/?cachebust=123 It should be firing the event "mousewheel" in main.js

It doesn't zoom or pan on the iPhone yet. It would be great if we could do pinch zooming.

Hmm, it could be that the scaling speed constant: scaleconst is too low, or high. Maybe this is what's causing the problem: https://github.com/aantthony/graph.tk/blob/master/ui.js#L290

:+1: I'm on a laptop (no mouse). Zoom is really essential.

I thought I remembered being able to zoom in the past, but I definitely can't zoom now. Google Chrome 77.

Just tried it on Chrome Mac Version 78.0.3904.97, and zooming was working (by using the mouse wheel). What operating system are you using @NSExceptional ?
