I have the same exact issue as outlined above. This is a chart that could become very useful and we have a very good use-case for it at my organisation, but we are not using it for the issues flagged above (colors are not persistent or customisable, they don't take the colors set in master dimensions, no legend). Fixing these quick things could make it a very valuable chart that people and companies couldactually use.
The extension in it’s current state is simply not designed to provide consistent colors.
If we want persistent colors I can see two options:
1. Use the “group” feature and then assign a color to each group. Pretty sure some coding will be required for this to work well.
2. Set the color of each node individually. This would give complete control over the color (and other attributes!) of all nodes and edges. The downside would be that it’s more complex to set up for the developers.
I am leaning towards implementing option 2 above, but I’m certainly open for other ideas and suggestions.
