         9 . The assistance device according to  claim 7 ,
 wherein the process further includes displaying, on the display device, a moving image of a simulation of the work machine in which the work part moves along the trajectory generated through the first operation screen, the moving image being superimposed on the image representing the shape of the work target.   
     
     
         10 . The assistance device according to  claim 7 ,
 wherein the process further includes displaying, on the display device, an image representing a shape of the work target predicted after the work part moves along the trajectory generated through the first operation screen.   
     
     
         11 . The assistance device according to  claim 1 ,
 wherein the process further includes displaying, on the display device, a second operation screen for operating the work machine such that the work part moves along the trajectory generated through the first operation screen, in response to the input from the input device.   
     
     
         12 . The assistance device according to  claim 11 ,
 wherein, on the second operation screen, the user can perform an operation for instructing the work machine to operate such that the work part moves along the trajectory generated through the first operation screen, using the input device.   
     
     
         13 . A work machine comprising:
