Be sure to take a look at the [d3-zoom docs](https://d3js.org/d3-zoom#zoom_transform). There you’ll find an example to reset a zoom transform, which you need to apply _before_ you remove the handlers so that your SVG can still update:

```js
    } else {
      svgOrigin.call(zoom.transform, d3.zoomIdentity);
      // Remove all *.zoom event handlers
      svgOrigin.on(".zoom", null);
    }

```
