QuickStart example lacks polish #22
Description
Its very clear that some fundamental polish is lacking from the quick start example https://panel-extensions.github.io/panel-reactflow/#quickstart:
- There is no input to "Start" but its visualized
- There is no output from "Finish" but its visualized
- Data flows from Start to Finish but there is no arrow or other visualization indicating this.
- The Graph is editable, i.e. I can drag new edges but not anchor them anywhere. This can mislead users.
So far I've not been able to see from the documentation how to add this polish.
