Do you want to avoid calling the update method if a user resizes your visual?

If so, you can detect a type of update by using VisualUpdateOptions.type (you get VisualUpdateOptions in the update method).

The type allows detecting an update type.

The update method is called every time any filter or selection is applied or there's a change in Formatting Panel for this visual.

You can call it whenever you want from your code. You just need to keep the update options or split update method into a few methods. We usually split update into the update and render.

The update indicates a change in data. The render indicates a rendering flow.
