Graphviz’s dot tool on Windows

I’ve created a java program to write a .dot file as I’m using Graphviz software to visualize some data.
There is nothing wrong with a code itself, but when I try to execute the following command in command prompt:

dot -Tpdf -o data.pdf

in a folder where my java code is located, I get the following error:

‘dot’ is not recognized as an internal or external command, operable program or batch file.

Sorry if the question was asked before, but the only similar question I found related to this problem is this one, however, it doesn’t seem quite clear to me how could it be helpful in this particular case.

Any help would be appreciated. Regards.
