Usage in VSCode

[jbriales]

I'd love to try this inside VSCode.
Could you complete the current TODO in the README for Usage in VSCode?

You can find the extension here:
https://github.com/nikeee/dot-vscode

It is currently not published to the store. You have to build and install it locally.

joaompinto/vscode-graphviz#38 will support it.
