Graphviz Viewer

Experimenting with a revised graphviz-viewer. Based on hpcc-systems/hpcc-js-wasm. UPDATE: Paul has updated the graphviz plugin to use this library. PR #10 hpcc-systems/hpcc-js-wasm Demo doesn't fit well in this frame. Pan around or look in another tab: demo HEIGHT 305


For some reason the .wasm files have to be at the same directory level as graphviz-viewer.js, so I just put everything there for now.

Created this roughly as follows:

npm install --save @hpcc-js/wasm find node_modules/@hpcc-js/wasm/dist -type f \ | xargs -I % cp % .
