Another two good Foam-like VSCode tools are Markdown Memo (https://github.com/svsool/vscode-memo) and Dendron.

I personally prefer vscode-memo to Foam. It doesn't have a graphical view, but there a couple other things it does really well, especially its (optional) support for flattened wikilinks to hierarchically organized notes.

Seconded. I've been using Foam for some time now and it's been great. Since it's all VS Code, it's also very hackable
