Pull Request Overview

This PR ensures the build script no longer defaults to a Debug preset and updates the Graphviz demo HTML to use the new package layout and display the library version.

• scripts/cpp-build.sh: Comments out the Debug build preset to avoid defaulting to Debug.
• hw-graphviz.html: Switches imports to the new local/dist and CDN modules and adds a version display element.

• [nitpick] The id placeholder_version is generic; consider renaming it to something like graphviz_version for clearer intent and consistency.

• [nitpick] It would be helpful to add a brief comment explaining why the Debug preset is commented out, so future maintainers understand the rationale.

# cmake -S . -B ./build --preset vcpkg-emscripten-Debug

The ?? chain only catches failures of the first import; if the CDN import on the next line fails, it will throw an unhandled rejection. Consider wrapping the combined import logic in a try/catch or adding a .catch() to the second import.

	await import("https://cdn.jsdelivr.net/npm/@hpcc-js/wasm-graphviz/dist/index.js").then(m => m.Graphviz);
	let Graphviz;
	try {

	Graphviz = undefined;
	}

[nitpick] The nested await import with chained .then() and ?? reduces readability. Consider splitting this into separate try/catch or sequential if blocks for clarity.

Suggested change

	const Graphviz = await import("./packages/graphviz/dist/index.js").then(m => m.Graphviz).catch(() => undefined) ??
	await import("https://cdn.jsdelivr.net/npm/@hpcc-js/wasm-graphviz/dist/index.js").then(m => m.Graphviz);
	let Graphviz;
	try {
	const localModule = await import("./packages/graphviz/dist/index.js");
	Graphviz = localModule.Graphviz;
	} catch (error) {
	console.warn("Failed to load local Graphviz module, falling back to remote module:", error);
	}
	if (!Graphviz) {
	const remoteModule = await import("https://cdn.jsdelivr.net/npm/@hpcc-js/wasm-graphviz/dist/index.js");
	Graphviz = remoteModule.Graphviz;
	}
