I ran it with no minified js and the result is the same unfortunately.
<!-- Fetch D3 Library -->
<script src="https://d3js.org/d3.v6.js"></script>
<!-- Fetch WASM -->
<script src="https://cdn.jsdelivr.net/npm/@hpcc-js/wasm/dist/index.js" type="javascript/worker"></script>
<script>
var hpccWasm = window["@hpcc-js/wasm"];
</script>
<!-- Fetch D3-Graphviz -->
<script src="https://unpkg.com/d3-graphviz@4.0.0/build/d3-graphviz.js"></script>
I remember graphviz 4.0.0 requiring D3.v6 but not sure about wasm
so I just grabbed the latest but earlier I did also ran it with @magjac’s example. And his example still runs with the configuration I have… but I’ll give your (@schmoo2k) recommendation a try.
