Research direction
Investigate the svg pan zoom library's current handling of mouse events and zoom functionality. Look at the demo provided (https://jsfiddle.net/chrvadala/f67qyfsd/) for a reference implementation. The feature requires implementing a rectangle draw interaction that triggers zoom to the selected area. Consider modifying the existing event handlers in the library to support a new 'select to zoom' mode. The issue is stale, so verify with maintainer if this feature is still desired before starting work.
