How to Create Power BI Report , Dataset and Modelling programmatically / using SDK

Hi All, 

Good Morning!!

I am looking for a solution to create Power BI Report & Modelling programmatically or using SDK. 

for example,

              1.  trying to create data modelling based on Tables, joins using metadata details in fileformat. 

              2.  if i want to create a report with 2 barchart, 1pie chart and few slicers , programmatically  i  these control i should have it from program.  

if its not possible for fully automated way, can we partially implement like editing dax query or MQuery dynamically. 

i have searched a lot but i didnt get any solution for this.  REST API is useful for editing published report or dataset in power bi service. 

I hope currently there is no API.  please suggest. 

Thanks in advance.
