This sample uses a JavaScript file that is built with Webpack. If you do not see a diagram, you may need to build first. See the readme.md in this directory for details.
This minimal sample contains as few GoJS modules as possible when building from the source. As a result, there is almost no interactivity possible, as no tools or the CommandHandler exist. There are also no Layouts (except the base Layout), Overviews, or Palettes.
If you look at the minimal-index.ts you will see what is dis-included.
For an example of building GoJS from source with all modules, see the Maximal project adjacent to this directory.
