Hi Martian Just to expand on Mario’s answer: the D3 plugin is little more than a tech demo to show how a third party library can be integrated with TiddlyWiki. In particular, the way that data is passed to it doesn’t easily permit the data to be created dynamically. I agree that the best way forwards for your use case is likely to involve improving the D3 widget itself.
