Some generic queries

I have following queries about PowerBI :

1. Does it have provision to use any programming/scripting language to manipulate data? for example when we use excel for generating reports we can manipulate data or any processing logic in VBA/VBScript.

1. Is it necessary to have datasets in standard formats?

1. Can we apply different filters for different graphs in the same dashboard?

1. Can we create any kind of UI on the dashboard which can get inputs from user which will change the reports or graphs dynamically?

1. Do we have provision to deploy it as any other Web Application? or we have to use PowerBI platform only to deploy the dashboard?
