Control process automatic visualization method based on dagre arrangement

The invention provides a control process automatic visualization method based on dagre arrangement, which comprises the following steps of: firstly modeling a control process into a directed acyclic graph, then storing information of the directed acyclic graph by utilizing two JSON (JavaScript Object Notation) files, then drawing the directed acyclic graph, and finally visualizing the drawn directed acyclic graph. According to the method, the automatic arrangement of the industrial control process is realized based on the dagre, the visualization of a complex control strategy is realized, and the readability of the control strategy is improved; the visual graph can be automatically generated only by filling the character information of the elements of the control strategy by the user, so that the time required by manual drawing and beautifying is shortened; the method is suitable for hierarchical structures such as edge activity networks. According to the method, the control process is modeled into the direct
