The building dimension is given as a $10$ by $13$ grids, with each grids represents a $10$ by $10$ unit space.

Give the numerical closeness ratings as: A$=10,$ E$=5,$ I$=2,$ O $=1,$ U $=0$ and X $=-10$

Construct a relationship diagram based on the material flow matrix and then:

Use graph$-$based method to construct the graph that represents the adjacency of a layout, and calculate the efficiency score. $($Just need to create the graph$)$
