Add zooming

[lemmy]

Assuming the rendered graph is large, zooming in/out would be a nice addition.

Indeed. To be completely honest though, it is probably not going to happen unless someone sends a pull request, I won't be able to work on this feature myself.

@thoorp I have no idea what "svg-Pan-zoom" is supposed to mean.

[ronatartifact]

The code seems to indicate that the output format can be selected but I can not find where to say that I want SVG rather than JPG. This will solve the zoom problem since the output file will support zoom.

@ronatartifact You choose the format by specifying a file with the desired file extension. These are the supported formats and their extensions:

JPEG("jpg"), PNG("png"), GIF("gif"), TIFF("tif"), BITMAP("bmp"), SVG("svg"), DOT("dot")
