I have been trying to figure out what is a mural or what is street art and the difference between the two (if there is) . What is the difference between the two ?

What would be such kind of art be labelled ? Graffiti, street art or something else ?

Update - there are no proper tags for the questions hence using canvas which is absolutely wrong (but is the closest among all others tags IMHO).
