How to install graphviz on windows?

I am trying to install Graphviz( 2.47.1-win64.exe) on windows 10. After downloading and installing I don’t see any desktop shortcut not in the installation folder. only uninstall file is available in graphviz folder after installation.

I watched few videos and added the path to the environment variable but still, I am unable to run Graphviz.

I want to visualize the decision tree generated from weka software using Graphviz so that i can customize and save it.

Kindly guide me through the process.
