The view is a graphic that is displayed on the UI. There are different types of views and each one of them is drawn in a different way (ex: image and text).
To create a view, you have to call the function canvasUI.view.new(id, type). The first argument is the id and the second argument is the type of view. The returned value is the view. That is an example:
const text = canvasUI.view.new("text-1", "text")
Every view has some properties that can be used to modify how it is drawn (ex: text). To change a property, you have to use the .set(property, value) method, like so:
text.set("text", "Hello World!")
