Using canvas instead on SVG too render #25

Open ganeshgore opened 3 years ago

For bigger schematics (CRC.json) the rendering takes much longer. Do you believe using d3 canvas render instead of SVG will improve the performance?

Use this flag to debug what is actually taking so long: https://github.com/Nic30/d3-hwschematic/blob/master/src/d3-hwschematic.js#L65

I think that the problem was the the layout (the algorithm which resolves how wires will be routed and components placed, not the actual rendering), layout is generated by elkjs, the options have great affect on performance https://www.eclipse.org/elk/reference/options.html (I picked something default, but it can be user overriden.) (the layout can be also precomputed, if necessary, but there is problem with expandable components as each expansion state is a new graph which has to have layout resolved)
