[Feature request]: Panzoom extension

[vasabi8]

Hi
Unfortunately, I did not find Panzoom integration with Dash.
This extension creates a widget that lets the user pan and zoom/
It would be nice to add this feature.

If someone has already integrated this extension, please share a solution.

Thanks,
Vasyl

@vasabi8 Have you tried using a dash callback to link a slider or a button that would let you control the zoom level? e.g.

n = 0.1  # Change this for scale
@app.callback(Output("cytoscape", "zoom", [Input("my-slider", "value")])
def update_zoom(slider_value):
  return n * slider_value

@xhlulu I tried your suggestion and it does work. However, it seems like it zooms on the upper left corner. And since the user cannot add his own pan values I can't seem to figure out how to fix that
