Investigate distributing a non-WASM build

[mdaines]

It's not possible to use WASM in some environments. For example, because of a Content Security Policy.

Emscripten can build a JavaScript-only version of Viz.js by using the setting WASM=0, so this seems to be mainly a matter of how to structure the build, and publish such a package.

Did you try this?

@lborgman Yes, thank you for reminding me. I took another look at this recently.

Emscripten has a setting that will output a fallback JS file for browsers than don't support WebAssembly (WASM=2). I was able to get Graphviz/Viz.js to build using this setting and successfully render graphs with the fallback.

It seems like a reasonable option, but I need to sort out how it would be packaged.
