The circle graph divides into ten sections, nine representing the Western Front (France) for 90% of 3.8 million German forces and one section for the Eastern Front (Russia) for 10% allocation, as per the Schlieffen Plan.
To create a circle graph representing the allocation of German forces according to the Schlieffen Plan:
Total German Forces: 3.8 million men
Allocation for Western Front (France):
90% of the forces were designated for the Western Front.
Calculate 90% of 3.8 million:

This represents the number of men allocated for the Western Front
Allocation for Eastern Front (Russia):
10% of the forces were allocated for the Eastern Front.
Calculate 10% of 3.8 million:

This represents the number of men allocated for the Eastern Front (Russia).
Visually representing this on a circle graph:
Divide the circle into ten equal sections.
Label nine sections as "Western Front (France)" and one section as "Eastern Front (Russia)."
This representation visually demonstrates the allocation of approximately 90% of German forces for the Western Front (France) and around 10% for the Eastern Front (Russia) according to the Schlieffen Plan.
