-`text`: `text` can represent either node text or edge text. For node text, the node coordinates are automatically used as the text coordinates. For edge text, an appropriate coordinate is computed based on the type of edge. In some scenarios, text positions can be adjusted and dragged. Therefore, our text data in LogicFlow provides coordinate attributes.
