Find a way to show when there's no prediction

This is not completely necessary for use, but for showing the app, it's important to know when the model has no predictions to offer and we should try another word

Probable we can show an image of something empty in the space the prediction appear, behind the boxes with the actual predictions.

Something like this. We can ask mutanto for one.
