title: Graphviz's dot tool on Windows
body: <p>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:</p>
  <blockquote>
  <p>dot -Tpdf data.dot -o data.pdf</p>
  </blockquote>
  <p>in a folder where my java code is located, I get the following error:</p>
  <blockquote>
  <p>'dot' is not recognized as an internal or external command, operable program or batch file.</p>
  </blockquote>
  <p>Sorry if the question was asked before, but the only similar question I found related to this problem is <a href="https://stackoverflow.com/questions/31727211/graphviz-dot-file-failing-to-compile-in-windows-emacs">this</a> one, however, it doesn't seem quite clear to me how could it be helpful in this particular case.</p>
  <p>Any help would be appreciated. Regards.</p>
