title: Implementing pan and zoom in jsPlumb
body: <p>I am working on a project that involves creating flowcharts using *jsPlumb(*Community edition). The community edition does not have pan/zoom functionality built in. he project doesn't require all the features offered by the paid version(Toolkit Edition).So, investing a hefty amount on the paid version is not an option. Are there any proven ways to accomplish pan/zoom using the community edition?</p>
