As I indicated in a comment to the answer on your earlier question, while most of the reports only give approved visas, you’ll find full data, per category and per year, on this page, in the section titled “Nonimmigrant Worldwide Issuance and Refusal Data by Visa Category”.
The reports include the following columns:
For data per country, I believe you’ll have to use the data for visas issued and the refusal rate per country to extrapolate the total number of applications (it will be slightly off because there a a few minor cases other than just issued and refused):
total = issued / (1-refusal rate)
