Call public update(options: VisualUpdateOptions)
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.

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.
